Special gate valve
Besides the common gate valves, We also makes cryogenic gate valve(Extended bonnet), bellow sealed globe valve, Jacketed gate valve, with bypass gate valve.By-Pass and Drain Connections,Indicator and Locking Devicesetc.Conduit Gate Valve
Application
widely used in oil, natural gas, long-distance pipelines and gas fields Valves used in forging or casting body, the gate designed with diversion holes, non-diversion holes; single discand double disc structure; Seat used bi-direction seal seat which mainly based on the metal seat sealing and assisted with soft seat sealing as a second type of seal. The series of parallel type gate valve has rational design, compact structure, sulfur resistance, corrosion resistance, wear-resistant, reliable sealing, and light torque of switches, easy-to-use.
