Cryogenic Gate Valve

GAIRUI Cryogenic Gate valve refers to the valve with working temperature below -110Degree C and widely used in area of LNG, LPG and other cryogenic medium. There are two different types of bonnet designing. One is bolted bonnet, i.e. the body is connected with bonnet by bolts & nuts with spiral wound gasket(If required, metal ring gasket could be provided) between. And the other type is welded bonnet, i.e. the bonnet is welded to body directly. Cryogenic Gate valve is used to connect pipe and fitting or its accessories. Flanged connection has the features of easy installation, good connection strength and good excellent sealing performance. The flange connection consists of flanges, bolts, nuts and gasket. When we fasten the connecting bolts, it would press the sealing gasket between the flange which would have elastic deformation and fill all the small space between the two flanges' sealing face, thus to realize the good sealing.
