Introduction of Cryogenic(Low Temperature) Ball Valve
PCTFE Soft Seated, Flanged
Cryogenic 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. 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.
The proportions of XHVAL cryogenic ball Valves can be customized to fit specific customer applications. The ball can be a full bore(same internal diameter as the pipeline) or a reduced bore (smaller internal diameter). Each unit is made to the highest industry standards.
Cryogenic Valves Industrial Applications
Liquid Gas Tanks – Liquid nitrogen and other cryogenic gases are stored in tightly sealed LNG tanks. The tanks are fitted with ball valves for nitrogen gas to allow the dispensation of liquid gas to other tanks whenever necessary.
Power Plants – liquefied natural gases are becoming a preferred source of energy. Power plants store them and use cryogenic ball valves to control their transfer through special pipelines.
LNG Ships – specially designed ships with LNG tanks are used to ship cryogenic gases. They are fitted with cryogenic ball valves to load, offload, and maintain the integrity of the gas during transport.
Cooling Systems – cryogenic ball valves are used to release controlled amounts of LNG to cool high heat scientific operations like Nuclear Magnetic Resonance.
