Cryogenic Ball Valve
Cryogenic ball valves are valves that applied at 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. 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.
Cryogenic Ball Valve Features
● The fluid resistance is small, and the sealing surface is less attacked by the media.
● Open and close less effort.
● The flow direction of the medium is not restricted, not disturbing the flow, not reducing the pressure.
● Simple shape, short structure length, good manufacturing technology, wide range of application.
