Cryogenic Testing of Valves – Testing to Specifications

We DBV valve group co., ltd have done cryogenic test ing as customers require by the third party like TUV,BV,SGS,NATIONAL QUALITY SUPERVISION AND INSPECTION CENTER OF VALVE, etc .
In concert with our cryogenic valve fabrication capabilities are facilities for cryogenic testing of valves in liquid nitrogen at –324oF. This equipment allows us to verify our own work as well as test valves for other manufacturers and end-users. Three special insulated stainless steel tanks of varying sizes are used for the tests. A large inventory of stainless steel flanges, bolting, test fixtures and fittings is maintained to fit all common cryogenic sizes. For seat leakage measurements we utilize a bank of various capacity flow meters. For shell, gasket and stem seal leak testing a Helium leak detector with a sensitivity of two ppm is used.
