Cryogenic top entry ball Valve
A cryogenic top entry 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
The series of valve is FUVALVE which make improve combined with foreign advanced technology , for low temperature condition and special research and development , The top entry structure , can meet online service or replacement valve trim , special structural design , making dismounting more easy ,and further improve maintainability of valve . The use of advanced piston seal structure , and back pressure ring design , ensure the sealing reliable , when cavity pressure abnormal rises , can make pressure life on request of pressure relief direction by client . The unique loosed against measures and reasonable parts material configuration , further enhance the overall performance and service life of valve . This series of valve can be widely used for liquefied natural gas ( LNG ) , aerospace ,metallurgical and other areas in the low temperature conditions.
