Piston & Bellow Sealed Valves

Piston valves and bellow sealed valves are two types of industrial flow control valves used to control the flow of liquids, gases, or steam in pipelines. These valves are crucial components in industrial processes that require precise control and reliable sealing. 

Piston valves use a movable piston within a cylindrical chamber to create a seal that prevents leakage. These valves offer excellent sealing capabilities, making them suitable for high-pressure and high-temperature applications. They also provide reliable isolation, minimizing the risk of leakage.

 

Bellow sealed valves have a flexible metallic bellow as the sealing element. The bellow acts as a barrier between the fluid or gas and the environment, which expands and contracts with changes in pressure, temperature, or movement. This design ensures a reliable seal, making bellow sealed valves ideal for handling corrosive and toxic fluids, as well as high-pressure and high-temperature conditions. They are commonly used in industries such as chemical processing, oil and gas, pharmaceuticals, and petrochemicals.

 

The choice between piston and bellow sealed valves depends on the specific requirements of the application. Factors such as operating conditions, pressure, temperature, and the nature of the fluid or gas being handled play a significant role in determining the appropriate valve type.
