Low Temperature Gate Valves

① To avoid abnormal pressure rise in the middle chamber, pressure relief opening is fitted at the inlet side of disc. ② The length of the top of bonnet depends on the working temperature of valve to ensure reliable sealing of stem packing.③ Use reasonable materials for the components like packing and gaskets etc. according to working temperature. ④ Strict control of the chemical composition of materials and the mechanical performance index such as

Flat Gate Valves

Flat gate valves have two structural types, namely single disc carrying deflector hole and not carrying deflector hole. Ones carrying deflector hole are given smooth flow passage to adapt to oil and gas transportation and through ball etc. Application: Flat gate valves are suitable for Class150~900, PN1.0~16.0MPa, and -29~121℃ petroleum, natural gas, water and oil pipeline to cut off or put through the media in pipeline.
