Slab Gate Valve

Slab Gate Valves(Parallel type gate valves, Through Conduit Gate Valves)are widely used in oil, natural gas long-distance pipelines and gas fields as open/close control valves. Valves used in forging or casting body, the gate designed with diversion holes, non-diversion holes; single plate and double plate 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.
