Duplex 4A 5A 6A Gate Valve

4A OS&Y 10'' 300LB Gate Valve

4A OS&Y 10'' 300LB Gate Valve,Body Material:4A,Connection: RF Flanged,Operation: Hand wheel,API 600,Cast Steel Valve,Face to face ASME B16.10 API600 gate valves usually adopt a wedge-type gate, or a solid or flexible wedge-type gate structure. The gate should be completely withdrawn from the valve seat hole when in the open position, except the parallel double-disc gate. GW also produce the valves as below, API 600 OS&Y Gate Valve, API 600 Wedge Gate Valve, OS&Y
