The Adaptable 2–Way Ball Valve: Components, Specifications, and Applications

As one of the quarter-turn ball valves, the 2-way ball valve is widely employed in the control of the flow of gases and fluids by the operation of a handlebar or actuator at 90° on-off movements.

Differ from the 3-way ball valves, a two-way ball valve features two openings or ports, one for the inflow of medium, and the other for the outflow. On dismantling the valve, you’d find a ball with a bore that rotates in the valve; hence the name “2-way ball valve”.

Like other ball valves, you are bound to experience the enormous benefits of the two-way ball valve, for its sturdiness and excellent function in high pressure and temperature conditions, durability, versatility, as well as its ease of maintenance.

What Are The Components Of A  2 Way Ball Valve?

The first step in appreciating the intricacies of the 2-way ball valve is by familiarising it with its parts. Don’t worry; we’ve simplified the descriptions such that you won’t forget them in a hurry.

The following are some essential parts of a 2-way ball valve:

Construction of 2 Way Ball Valve

Construction of 2 Way Ball Valve

The Valve Body

The body houses other components of the valve including the ball, stem, and valve seats. The materials for constructing the valve body of the 2-way ball valve are selected depending on the volume of the media flow to regulate and operate conditions like high temperature and pressure.

Kinvalve offers various body materials for your specific requirements. The commonest housings are stainless steel and carbon steel, and we also supply you with other alloys such as Titanium, Bronze, Brass.

The Ball

The robust rotary ball is designed to rotate as controlled by the valve stem. Its center bore functions as an opening through which gases, scrapers, or liquids are transported.

Usually, the center bore is smaller or of the same diameter as the pipe it is designed for.

The valve ball could be floating – moving in a lateral position; or trunnion-mounted, where its position is fixed by a shaft.

When the 2-way ball valve with a floating ball is closed, a fluid media pressures the ball into the valve seats, giving it a tight seal.

Due to the high pressure and temperature operations, it is involved in, the ball is usually coated with ultra-tough coatings to reduce wear and tear.

Examples of coating for the valve ball are Tungsten Carbide, Chrome Plating, ENP Plating, Chrome Carbide, and Thermal Spray, and Cold Spray.

The Valve Stem

The valve stem does the important job of turning the ball to tightly shut off the valve. To keep you protected, the stem in two-way ball valves is usually blowout-proofed.

That way, you won’t be involved in an accident caused by a dislodged stem by mounting pressure in the valve.

The Valve Seats

The seats are discs sandwiched between the body of the valve and the ball. Thus, they provide a cushioning effect to the rotating ball and pressure relief in high-pressure conditions of the media.

There are two types of valve seats, according to their materials: soft-seated and metal-seated.

The soft-seated valve seats are constructed with plastic and are recommended for media with a temperature less than or equal to 180°C (356°F), as any additional temperature could melt the plastic.

On the other hand, metal-seated valve seats are made of metallic materials which can tolerate a medium of temperature above 180°C.

Since the ball slides around the valve seats as it rotates, there is the need for the valve seats to be coated to minimize friction and extend the service life of the seats.

Also, the reduced friction on the valve seats generates a low operating torque for the smooth working of the valve with low energy consumption.

The coatings for valve seats include the standard hard chromium; Tungsten Carbide, Chromium Carbide, and Nickel-Boron.

Body Gaskets

Body gaskets in a two-way ball valve are mainly flat and made of materials like metal or PTFE.

Gaskets encircle the stem of the valve to provide a sealing function after the valve has been closed. This helps prevent leakage of fluid or escape of trapped gas.

Stem Packing

This refers to the pattern of packings surrounding the valve stem, to ensure that the media within doesn’t leak from the space between the stem and the valve body.

There are two kinds of stem packing: one-piece design and two-piece chevron stem packing design.

Because of its durability, the two-piece chevron stem packing is used in applications where fluctuations in temperature and pressure is high, and where valve actuation is regular.

Handle or actuator

What the stem does for the ball, the handle or actuator does for the stem. Whereas you can manually operate the valve by turning the handle/lever, an actuator works by hydraulic, electric, or pneumatic actuation when the two way ball valves are designed with an ISO 5211 Mounting Pad.

Complete Range of 2 Way Ball Valve with Unique Features

This section will consider the body and ball hole designs of the two-way ball valve manufactured by Kinvalve.

The Body Structure

The 2-way ball valve can be constructed as a one-piece, two-piece, or three-piece ball valve.

1–Piece Ball Valve


One Piece Ball Valve

The one-piece ball valve is the simplest and cheapest for your pocket-friendly budget.

It is shaped from just one piece of material and best suited for undemanding projects where a selective flow rate of media is required.

This type of 2-way ball valve is common for its affordability, and it can last you for a long time even with infrequent use.

2–Piece Ball Valve


2 Piece Ball Valve

Unlike the 1-piece, the two-piece ball valve is composed of two different parts: the body and the connector.

Once the rotary ball is placed in the valve, the body, and its connector section are joined together as one.

The 2-piece ball valve features a full port or full bore design that works powerfully in a wide range of applications where a full flow rate is needed.

You would observe that regular pressure drop is minimal in the two-piece ball valve is minimal, and that phenomenon has kept your valve from cavitation-related damages.

3–Piece Ball Valve


Swing-out Boby 3 Piece Ball Valve

The 3-piece ball valve is the most complex, costly, and heavy of the 2-way ball valves because it comprises three individual parts.

You can only bolt or weld three-piece ball valves together in fixed pipework systems. However, you must be a specialist before perfectly fixing or disassembling a 3-piece ball valve.

Three-piece ball valves are useful in applications where recurring valve maintenance is necessary.

Connection Types

As a professional 2 way ball valve manufacturer, Kinvalve devotes itself to design and manufacture a range of two way ball valves with different end connections, including flanged end, threaded end, welded end, and tri-clamp ends.

Flanged Ball Valve

Kinvalve flanged ball valves are available in almost all international standard types of flanges, the main standards you can choose are ANSI Ball Valves, DIN Ball Valves, and JIS Ball Valves.

At Kinvalve, our flanged 2 way ball valves are designed with floating balls, with a size range of 1/2 inch to 12 inches. The pressure ratings are Class 150/300, PN10-40, and JIS10K/20K accordingly.

Threaded Ball Valve

Compared to flanged ball valves, Kinvalve threaded ball valves are small ball valves, with a size range from 1/4inch up to 4 inches.

All of our threaded ball valves have a working pressure of 1000WOG in the cast body.

When you refer to high pressure up to 1500PSI, 2000PSI, even 3000PSI, a forged body will be recommended.

At Kinvalve, threaded ball valves are also applied for the worldwide standards, there are mainly two series, NPT Ball Valve and BSP Ball Valve.

Welded Ball Valve

Kinvalve welded ball valves are usually used in the service where you don’t need to replace them regularly.

The welded ball valves create stronger joints than threaded ball valves or flanged ball valves do.

However, you still can maintain these welded ball valves easily because all of these ball valves are available in a 3-piece structure with a swing-out body design.

Tri-clamp Ball Valve

Kinvalve tri-clamp ball valves are designed with quick install clamps for quick cleaning and replacement.  These tri-clamp ball valves are also called tri-clover ball valves.

At Kinvalve, these ball valves are usually suitable for sanitary use and other industries. You can choose the tri-clamp ball valves in 3 piece ball valves or 3-way ball valves.

When you use these tri-clover ball valves for the brewing, beverage, or food industry, they generally need polish treatment and require the trim with food-grade materials.

The Port Style Of The 2–Way Ball Valve


2 Way Ball Valve with Full Port or Reduced Bore Design

The hole through the ball has different styles; they are full bore, reduced bore, and V-shaped bore designs.

Full Port Ball Valve

In the full bore or full port design, the ball hole is of the same size as the valve’s inlet and outlet openings, as well as the internal dimensions of the pipe it will be attached to.

The flow of gas or liquid through the full bore is full and unhindered. Applications of the full bore include pigging or hot tapping operations.

Reduced Bore Ball Valve

Generally, a ball hole with a reduced port is one pipe size smaller than the pipe it will be connected to.

Most one-piece ball valves have reduced ports and they restrict the rate of movement of gases or liquids through pipes.

In the oil and gas industry, the reduced bore comes handy in critical service operations.

V Port Ball Valve

Also known as the V Ball Valve or V Notch Ball Valve, the bore is shaped into a “V”, and is mostly applied in the control of flow velocities of media.

Seat Materials

At Kinvalve, 2-way ball valves also can be classified by the types of seat materials. There are soft seated ball valves and metal seated ball valves accordingly.

Soft Seated Ball Valve

At Kinvalve, soft seated ball valves are designed with the elastomer as the valve seats. The elastomeric seats together with the ball create a reliable sealing.

Kinvalve two way ball valves are available in PTFE seats as standard. But you still have the options of RTFE, PPL, PEEK, or Graphite seats for the specific applications, mostly the high-temperature services.

Metal Seated Ball Valve

When the soft seated ball valves are not suitable because of the temperature or the fluid characteristic, you still have another choice, the metal seated ball valves.

Kinvalve metal seated ball valves are recommended for applications with high temperature or abrasive fluids.

In general, metal seated ball valves can resist erosive attacks and withstand high-temperature. Sometimes, you also can choose the special alloy coatings for the seats and ball.

Applications Of The Kinvalve 2-Way Ball Valve

2-way ball valves are called multifunctional valves for their broad applications in pigging, gas processing, and other industrial and household purposes.

Kinvalve two-way ball valves are useful in industries like chemical and petrochemical, paper, food, pharmaceutical, aerospace, and automotive.

It contains the housing, two ports consisting of the inlet and outlet, and a boring ball.

To operate these, you will use a hand lever to turn them to a 90-degree angle to open or close the valve.

When the bore of the ball, inlet and outlet ports are in a straight line, the valve is fully opened.

The handle will enable you to rotate the ball on an axis, thus enabling you to open, regulate, or close the valve.

What Are The Main Components Of A 2 Way Ball Valve?

Components of a Ball Valve

Components of a Ball Valve

Here are the main parts of a 2-way ball valve:

Valve Body

It is the part that will house all the parts that make up the 2-way ball valve that assists in controlling the flow. The valve body operates by connecting the two sections of the pipe.

It protects all the internal components, and you can use it to access the external control systems that rotate the ball.


These are round disks that have the shape of a doughnut.

It works by forming a seal between the 2-way valve body and the ball.

Upstream seats are adjacent to the inlet section of the valves.

Downstream seats are adjacent to the outlet side of the 2-way ball valve.


It is a spherical substance with a hole or tunnel in the middle known as a bore.

The bore assists to form the flow path of fluids when it is in a coplanar position to the cross-section of the flow.


This part is a shaft that connects the outer part of the 2-way ball valve to the internal ball.

It, therefore, enhances the rotation of the ball within the valve.

Also, it has packings like O-rings and bonnet, and you can operate it manually, electrically, pneumatically, or hydraulically.

Stem Packing

This part is a flexible seal that will fit around the shaft, preventing media from escaping the 2-way ball valve.


This part will is on the outside of the device and assists you to rotate the stem of the 2-way ball valve.

It can be hydraulic, gear, lever, or motor-operated.


This part is the component that will house the stem packing and the stem.

Also, it may be bolted or welded to the valve body, and hard metal is the material construction.


It will distribute the load of the fasteners, thereby preventing cracks around the surface.

Lock Device

This component enables you to lock the ball valve position, either in an open or closed state.

What Is A 2 Way Ball Valve Flow Pattern?

The flow patterns describe how the fluid will pass from one port to another.

2-way ball valve flow patterns can offer a T or L flow pattern.

What Is The Difference Between 2 Way Ball Valve And 3 Way Ball Valve?

The differences include:


2-way ball valves are simple to manufacture, and they are also common in several industries.

It has a lightweight configuration making it practical for manual and automatic control of fluids and gases.

3-way ball valves will only have an easy installation process if it has a threaded end connection.

When you have to weld the end to prevent damage to the valve, you will partially disassemble the valve during installation.


2-way ball valves have two main parts.

The first part has the main body and one end connection.

The second part contains the other end connection and the valve trim.

3-way ball valves have three main pieces.

These pieces include the Centre component that will hold the two end connections and the valve trim.


Since 2-way ball valves have a simple design, they have a more excellent CV value than a 3-way ball valve.

Features like seats, seals, and usage are essential than the design.

End Connection

The nature of the design of 2-way ball valves makes them have limited types of end connections.

They will mostly have an end-threaded connection.

On the other hand, 3-way ball valves have a swing design.

This feature makes them suitable to have an end connection that you can weld.

Also, this makes it possible to have the butt weld ends and sockets.


3-way ball valves have an oscillating design making them easy to maintain than 2-way ball valves.

This feature enables other sections to remain intact as your service or clean the valves.

Three-Way Ball Valve

Three-Way Ball Valve

Why Are Handles Important For 2 Way Ball Valves?

Handles are vital since they enable you to close or open the valve.

When the handle is parallel to the pipe, it indicates that the valve is open, and when perpendicular, the valve is closed.

This visual cue assists you in knowing if the vale is closed or open.

Some examples of handles you can use with a 2-way ball valve are:

Lockable Handles

These handles allow you to apply more torque when opening or closing the valves.

It is a single, long bar that stems from the valve.

Detent Handles

Once you turn it and release the grip for this handle, it springs back to its original resting position.

Butterfly Handle

This handle is at the Centre of the valve and has two short bars that stem from its Centre on both sides.

It allows you to use your fingers to apply pressure on both ends in the same direction, either clockwise or anticlockwise.

Ball Valve Handwheels

This wheel is circular and allows you to open or close by twisting.

Also mention the available handle options, i.e. locking or detent type handles

How Is 2 Way L-port Ball Valve Difference From 2 Way T-Port Ball Valve?

Here is how these two compare:

2-way T-port Valve

This port can direct fluid to multiple locations concurrently.

They contain a third handle that can join the Centre to the other two ports simultaneously.

If the ball is in an open position, the fluid will pass via the valve at maximum pressure to one valve.

Also, the fluid will go to the other valve at slightly low pressure.

Two Way T-Port Valve

Two Way T-Port Valve

Applications of a 2-way T-port valve are:

  1. Combine the flow from two sources
  2. Split the flow between two sources
  3. Change the flow between different targets
  4. Enable the flow from separate sources to mix
  5. Change the flow between to sources

2-way L-port Valve

L-port valves contain a ball that will connect two adjacent ports.

Traditionally, they will direct the flow between the Centre port and one of the other two ports.

Here, the valve the opposite task and direct fluid from several sources.

For instance, the L-port valve will facilitate the capacity to direct fluid from 2 or more sources.

When you simply turn the handle, the position of the ball within the valve will change.

This action will change the source from where you are drawing the fluid.

An example is that when one tank becomes empty, you can get fluid from another tank.

Applications of a 2-way L-port valve are:

  1. Divert the flow towards one tank to another tank
  2. Alter the source of flow from one pump to another
  3. Change the flow of the source from one tank to another

Two Way L- port Valve

How Do I Choose Actuator Size For 2 Way Ball Valve?

It is complex to properly size actuators, and thereby you need trained experts to size them.

Choosing oversized actuators can cause damages to the stem of the 2-way ball valve and is a wasteful purchase.

Also, you can minimize the damage by using other parts like relief valves.

Choosing an undersized actuator means you will not be able to operate the valve on demand.

Operating on demand is vital in Emergency Shutdown Valves [ESDVs].

Some factors to consider when sizing actuators are the minimum and maximum supply pressure.

Also, you should not use normal pressure to size an actuator.

The actuator should operate when the supply pressure is at the lowest point or handle the maximum pressure safely.
