Cryogenic Extension ball valves are valves that are applied in the management and safe storage of matter at very low temperatures. They are built to withstand temperatures as low as -190°C to absolute zero (-238°F to -460°F ) and are thus also known as low temperature ball valves.
Series - 150 To 2500
They are equally capable of handling extremely high pressures that result from such extreme temperatures. Our cryogenic ball valve consists of 3 parts: an actuator, a stem, and a ball. The actuator is the outermost part for which we offer a variety of designs. It is connected to the stem which is a rod-like structure that houses the floating ball. When the actuator is turned, the stem also rotates and repositions the ball accordingly.
Design Features
- The fluid resistance is small, and the sealing surface is less attacked by the media
- Open and close less effort
- Simple shape, short structure length, good manufacturing technology, wide range of application
- The flow direction of the medium is not restricted, not disturbing the flow, not reducing the pressure
