Side entry cryogenic ball valve
A cryogenic ball valve is made to specifically withstand temperatures below freezing point in industrial applications. It is generally made from stainless steel and bronze. It also comes with an extended bonnet for protection against extreme temperatures.
Products Introduction
Side entry cryogenic ball valve is largely applied to aerospace , metallurgy , solar panels and other high-tech field , also can be used in food processing , production and medical industries , the series of ball valve body usually is Flanged , convenient match to pipe connection , high performance lip-seal the sealing ring to ensure reliable seal At the same time , the optimization of the seat structure design and reasonable material configuration , to make valve withstand of cryogenic conditions test . extended stem diameter greatly increase the valve safety operation , assures stem not distortion . unique over-pressure automatic pressure release function can guarantee the body cavity pressure is ot more than 1.33 P . Fuvalve designs & manufacture cryogenic ball valve fully considered every detail , maximum meet low the reliability of cryogenic condition to valve requirements
