A Stainless Steel Flanged Ball Valve

What are the types of Stainless-Steel Flanged Ball Valves concerning the Material Used?

Simple steel is more susceptible to rust because it’s iron-based material.

The stainless steel contains more chromium and that is why more rust-resistant.

The stainless steel’s quality of being rust resistant gives it a longer life span.

The addition of extra nickel gives it longer life and the ability to sustain in comparatively more harsh environments.

The characteristics of stainless steel can be modified according to the requirement by adding different types of materials with it.

So, the classification is done based on extra material added to it.

There are three different types of stainless steel, which are commonly found in the market. The details are as below:

Austenitic Stainless steels Flanged Ball Valve:

Austenitic Stainless steel consists of chromium and nickel as an alloy.

These materials are hardened and non-magnetic in a way.

The stainless steel consists of Chromium and Nickel is commonly known as T300 series stainless steel.

The addition of Manganese with Chromium and Nickel made the stainless steel T200 series stainless steel.

Application: The typical application of such valves are pulp and paper mills, Chemical Processes, Seawater related applications, Production and Transport of sulfuric acid, Gas Washing, Pharmaceutical Industries, Oil pipelines, and Oil Refining

Ferritic Stainless Steel Flanged Ball Valve:

When the Stainless Steel Flanged Ball Valve is fully open or fully closed, the sealing surface of the ball valve remains isolated from the medium. This property of being isolated keeps the body of the valve from erosion.

What is the Working Environment Temperature Ranges for the Stainless Steel Flanged Ball Valve?

The temperature of the working environment of a valve is defined based on the material used for the construction of the seat of the valve.

The seat is the interior surface of the body which contacts the body of the valve to prevent leak. The seat of a valve can be seen below image.

The Seat of a Stainless Steel Flanged Ball Valve

There are two types of valves available with respect to the material of the seal. The seals are made of metal and other soft materials.

The hard seats are usually made of metal. This metal includes Carbonate and Hard faced metal (5H & 6H).

The carbonite seats are made of hard carbon. These hard carbon seats have excellent heat resistance properties and can bear up to 500^oC.

Metal Seat (5H) is formed by using the surface of a 316-grade stainless steel seat and thermal-spraying it with chrome and nickel alloys. After this, the metal seat (5H) becomes capable of bearing high temperatures up to 300^oC.

In the case of Metal Seat (6H), the ball, as well as the seat, is thermal-sprayed with nickel and chrome. The process of spraying makes it capable of bearing temperatures up to 500^oC.

The hard seats can bear more temperature due to their materialistic properties.

The Stainless-Steel Flanged Ball Valve with Hard Seat can bear up to 500°C.

The disadvantage of using Stainless Steel Flanged Ball Valve with Hard Seat is that such Stainless Steel Flanged Ball Valve can have some leakage with time.

The other type of seat available is the Soft Seats.

The soft seats are made of soft materials like PTFE. The PTFE seats possess high chemical resistance and give an excellent sealing performance. The maximum service temperature is 200^oC for the seats made of PTFE.

There is another material used in the seats of Stainless Steel Flanged Ball Valve that is Hypatite PTFE. The Hypatite PTFE is made of modified PTFE. Hypatia PTFE can be used at the working temperature of 260^oC with excellent resistance to creep compression.

C/F PTFE (carbon fiber filled PTFE) is another material used in the seats of Stainless Steel Flanged Ball Valve. The seat of Stainless Steel Flanged Ball Valve has high mechanical strength and can bear temperature up to 260^oC.

What are the Pressure Ranges of a Stainless Steel Flanged Ball Valve?

The pressure range of the stainless steel flanged ball valve varies with the grade of the stainless steel material used and the design.

The pressure handling capability of the Stainless Steel flanged ball valve also varies with the type of Stainless Steel Flanged Ball Valve.

Two Main Types of Stainless Steel Flanged Ball valves are Floating Ball valves and Trunnion Mounted Ball valves.

The Floating Ball valve has a ball without any trunnion inside the valve body.

When the media flows through it, it pushes the ball against the seat under medium pressure.

As all the pressure is bear by the seat, therefore good seat material is required to withstand the workload.

Due to the reason of the unavailability of high pressure handling capability material the Stainless Steel Flanged Ball Valve is mainly used for low-pressure applications.

The trunnion mounted Stainless Steel Flanged Ball Valve uses a spring mechanism to push the upstream seat against the stationary ball.

This way the only area exposed to the pressure in the back of the seat.

This mechanism gives the capability to Stainless Steel Flanged Ball Valve to handle comparatively high pressure.

Different pressure classes are defined according to the type of material used for the seat. This includes JIS and PN standards.

An example of the pressure handling capability of the Stainless Steel Flanged Ball Valve as per the material used for the seat can be depicted from the figure below:

Is Stainless Steel Flanged Ball Valve Available with Actuators?

The Stainless Steel Flanged Ball Valve can be operated using actuators.

The actuators make the operation of the Stainless Steel Flanged Ball Valve automate.

The Stainless Steel Flanged Ball Valve also comes with an actuator mounting pad.

The mounting pad is useful to mount the actuators on the valve without any extra hardware changes.

ISO 5211 allows the direct mounting of actuators or gearbox on the mounting pad.

A mounting pad is used to directly mount gearbox or actuators on a stainless steel flanged ball valve. As a result, no extra equipment, be it couplers or brackets, is used.

With the help of a mounting pad, there is less chance of corrosion. There are three main options available of actuators for the stainless steel flanged ball valve.

Pneumatic Actuators:

The valves operated by pneumatic actuators have an assembly of spring, diaphragm, adjusting screw, and the stem.

The adjusting screw applies pre-load on the spring to engage the valve in its failure position.

Without the pneumatic signal on the diaphragm, the valve remains in this position.

The diaphragm holds the air coming as a pneumatic signal to adjust the position of the spring to open or close the valve.

Hydraulic Actuators:

These works in the same way as the pneumatic actuators but instead of the diaphragm, it has a piston to move.

The pressure is inserted by some liquid to move the piston and open or close the Stainless Steel Flanged Ball valve.

Electric Actuators:

Electric actuators include servo, stepper, or simple DC motors. Indirectly mounted valves, manual handles are replaced with electric motors with some positioning mechanism.

The servo and stepper motors have a built-in position detector mechanism.

The servo-based actuators utilize the information of the encoder to know its position while the stepper motor counts its number of steps to estimate its current position.

In electric actuated stainless steel flanged ball valves, the control board is the brain of the valve and receives the signals of opening and closing the valve.

What Sizes are Available in Stainless Steel Flanged Ball Valve?

The size of a Stainless Steel Flanged Ball valve is the measurement of the connector diameter. There are different sizes are available for a Stainless Steel Flanged Ball Valve.

These sizes vary from ½” to 12”, depending upon the requirement and construction of the Stainless Steel Flanged Ball Valve.

Selecting a valve that does not fit properly in an area is just an extra cost.

How is a Stainless Steel Flanged Ball Valve Better Than a Carbon Steel Flanged Ball Valve?

The difference between Stainless Steel Flanged Ball Valve and Carbon Steel Flanged Ball Valve is in the composition of the material. Both the materials are made of steel but the difference is in the alloy.

The Stainless Steel Flanged Ball Valve, as the name shows, made of Stainless Steel. Stainless Steel is made of Iron-Based material like steel.

When steel is exposed to oxygen, they undergo a chemical reaction called oxidation. The chemical process of Oxidation changes their properties.

Due to which the iron-material changes to reddish-brown metal. This brown metal, at some point in time, will disintegrate itself completely.

Stainless Steel is used to protect Steel against oxidation. It consists of minimum chromium content of 10.5%.

The chromium isn’t susceptible to oxidation. The properties of the chromium allow it to get exposed to oxygen and help to protect against oxidation.

The chromium used in the Stainless Steel Flanged Ball Valve makes a protective layer of chromium that stands between oxygen and steel which protects it from corrosion.

Stainless Steel Flanged Ball Valve

The Carbon Steel Flanged Ball Valve is made of, as the name suggests, Carbon Steel. Carbon Steel is characterized by a high carbon steel content.

The carbon steel content used in it is about 2.1% by weight.

The use of carbon changes the chemical properties of the Steel and makes it harder and stronger.

But on the other hand, Carbon doesn’t create any protective layer between Steel and environmental oxygen.

Due to this, steel exposes to environmental oxygen and causes corrosion. Moisture can be a big problem from Carbon Steel Flanged Ball Valve.

Hence, Stainless Steel Flanged Ball Valve is more suitable for applications where it is important to protect the Stainless Steel Flanged Ball Valve from rust.

This makes it to be useful in marine-related applications.

What the Difference Between ASME, ASTM, or API Stainless Steel Flanged Ball Valve?

All of these organizations introduced different standards for different parameters of the valve. All of the standards define the specific manufacturing process of the material and the exact composition of pipes, connections, and flanges.

ASME B16.10 defines the exact end-to-end and face-to-face dimensions of the straight valves, and center-to-face dimensions of the angle valves.

The purpose of this standard is to ensure installation interchangeability for a given material, type, size, and connection. This category applied to stainless Steel Flanged Ball valves.

ASTM 351 is the standard that defines standard specifications for casting, Austenitic, for pressure-containing parts.

There are further different grads within a standard, which are different for different materials. There are ASTM 351 CF3 and CF8 for SS304 and CF8M for SS316.

As per the standard, the steel shall be made by the electric furnace process with or without the help of separate refining. Also, that the ASTM A351 cast part must receive heat treatment followed by quench in water or rapid cooling.

For the inspection of all types of valves, there are some defined standards known as API (American Petroleum Institute) standards.

Affiliation of this standard proves sound engineering, safe manufacturing processes, and environmental protection.

The main goal of this standard is to mitigate risks in equipment failure. There are around 700 standards developed by this organization.

There is a standard API 598 for valve inspection and testing. It has some defined acceptable leakage rates for different liquids and gas testing.

There must be no visible leakage for the shell and back seat. The Stainless Steel Flanged Ball Valve follows the API 598 standard.

There are few API standards defined especially for valves or Stainless Steel Flanged Ball Valves. API 600 ensures the specific features in the valve.

This standard is related to the specifications of the Body wall thickness, Bonnet wall thickness, which includes, Flanged Ends, Butt-Welding Ends, Body Seat, openings, and few other things.

API 6D gives the specifications for pipeline valves which includes Ball Valves. Such as Stainless Steel Flanged Ball Valve.

This standard specifies the requirements for the manufacturing, design, testing, and documentation of the Stainless Steel Flanged Ball Valve.

API 608 covers the class 150 and Class 300 metal balls of Stainless Steel Flanged Ball Valves and are used in on-off services.
