Ball valve

Ball valve

Other types of ball valves, such as welded and threaded ball valves, are comparatively intricate to install and uninstall than a flanged ball valve.

This makes flanged ball valves stand out as a better alternative when you consider installation and uninstallation simplicity.

The exterior parts of the flanged ball valve are also quite different from other ball valves.

Besides, flanged ball valves are suitable for low and high-pressure applications.

Most of the other ball valves are often suited for a specific application, either low, medium, or high pressure.

In other words, a flanged ball valve is relatively versatile compared to different types of ball valves.

What is the Ideal Size of a Flanged Ball Valve?

Ideally, flanged ball valves are manufactured in an array of standard sizes.

Most applications also use the standards sizes hence making it easy to find the ideal size from a wide range of options available.

Even so, you can also find customized flanged ball valve sizes.

This depends on the type of your application and the particular manufacturer you’re considering purchasing the item from.

In general, though, the ideal size of this component is solely dependent on the specific intended application.

What Parameters are Used for Categorizing Flanged Ball Valves?

Ostensibly, flanged ball valves are categorized in numerous classes depending on different aspects.

There are several parameters used for categorizing this type of ball valves, and the main elements include the following;

Ball valve

Ball valve

· Design

Technically, flanged ball valves come in three major designs: floating, trunnion mounted, and orbit ball valves.

A floating design detects elevation changes occurring in liquid-free surfaces hence opening and closing the valve accordingly.

This type maintains the level in the cold water header tank, which is vital in regulating the pressure of the hot water system.

Most of the float flanged ball valves are usually used in domestic systems.

Trunnion mounted design, on the other hand, uses trunnion or lower stem to support the ball that is within the valve body.

In contrast, the ball in the trunnion is fixed and hardly floats.

Furthermore, the ball is centered by the stem at the top and trunnion at the bottom.

The orbit ball valve, however, uses a rotating cam action and rotating motion to create a seal.

Its efficiency is based on the number of turns of the hand-wheel.

· Ball Access

This categorization merely looks at the flanged ball valve from the aspect of point of entry.

Some come with top entry, whereas others come with side entry designs.

In the top entry, the balls are assembled from the upper section of the device.

This allows easy access to the balls and seats, especially during maintenance, without interfering with the valve.

Inside the entry, the balls are assembled from the side section of the device and mostly in two or three pieces body.

· Body Assembly

Classifying under this category is based on the type of housing of the flanged ball valve.

Some of the available designs under this category include the following;

  • One-piece – It consists of a single body
  • Two-piece – It has two pieces; one at the end connection and the body.
  • Three-piece – It consists of two pieces and a body
  • Welded body – It is assembled in a wholly welded construction with no leak paths through-bolt connection.

· Number of Ports

This classification is based on the number of ports the flanged ball valve contains.

Ordinarily, the standard design consist of two-port; one inlet and one outlet.

· Bore Size

This classification is based on three different elements;

  • Full bore – It is also known as a full port valve. This type has a similar bore diameter as the pipe hence no extra friction.
  • Reduce bore – In this case, the valve introduces friction losses in the system. This category of the valve is ideal where turbulence and pressure drop in the flow are not major concerns.

· Seat Type

Flanged ball valves mostly come with either metallic or soft Teflon types of seats.

What Factors Determine Reliability of Flanged Ball Valve?

The efficiency and reliability of the flanged ball valve are largely dependent on whether it is properly assembled.

Of course, incorrect assembly is likely to damage the valve or compromise its functionality in fluid control systems.

Here are the integral elements revolving around the reliability and efficiency of this device;

· High-velocity Liquids

If the flanged ball valve is intended to operate frequently on liquids with high velocity, ensure you check its drawing or diagram.

This is essential in minimizing the possibility of seat deformation, particularly when applied in high-temperatures and highly-pressurized pipelines.

· Valve Selection

It is a vital aspect to consider with design specifications, which meet the temperature and pressure conditions required.

Ensure you look into the seat material since fluids containing abrasive may degrade the seals.

· Degree of Valve Opening

The flanged ball valve is in the category of on/off valves.

Therefore, there is a need for high maintenance and care.

It helps in making the valve open or close fully when installed in a pipeline system.

The valve opens leads to seat erosion and can cause leakage.

Also, when storing valves, ensure that they in a fully open position.

· Valve Mounting

Check the pipe bore to verify that there is no weld spatter, rust, or scale particles remaining inside before mounting the valve.

Locate the flange bolts and ensure they are tightened evenly when mounting the flange end ball valve.

· High Temperature and High-Pressure Service

The manufacturer’s recommended pressure and temperature rating should be the appropriate guide for the maximum range the valve can withstand.

Even so, you require reference to valve distributor for assurance of suitability when the ball valve is subjected to various conditions.

· Valve Disassembly

Ensure you remove the fluid completely from the valve internals before dismantling the unit from the pipeline for repair and maintenance.

Also, discharge the pressure trapped in the body completely before disassembling the flanged ball valve.

How does a Flanged Ball Valve Work?

The working principle of a flanged ball valve depends on the specific design.

Floating design is, however, the most commonly used in several applications.

In essence, the ball in this design is suspended in the flowing substance.

The ball stays in position by compression of two elastomeric seats against it.

The shaft attached at the top of the ball allows it to turn in a quarter 90-degree movement.

This enables it to switch the valve from an opening to a closing position effortlessly.

While at it, a load is applied to the ball. The ball is then pressed against its seats whenever the shaft is moving.

When the flange ball valve works under medium pressure, the floating ball moves against the downstream seat.

The valve’s seal belongs to the single-sided seal.

Technically, the valve has an upper stem hence allowing the ball to have a light displacement.

When the flanged valve is closed, the ball is pressed against the sealing surface.

This takes place as a result of the action of pressure to release the sealing.

A flanged ball valve with a smaller diameter is suitable for medium and low pressure.

Principally, the floating design is lightweight and economical.

Thus it can suit a bore size of 10”.

In case the bore size is more than 10”, the valve seats may fail to withstand a heavier ball.

Ultimately, this would lead to the malfunctioning of the flanged ball valve.
