Gate Valves

Slab Gate Valve -- Through Conduit API 6D WCB

Through-conduit slab gate valves manufactured to API 6D with floating self-relieving seats for oil, gas, and refined product pipeline isolation. The slab gate design provides full-bore piggable flow path with double block and bleed capability. Floating seats seal independently of line pressure direction, making the valve truly bidirectional. Low operating torque and anti-static design ensure safe, reliable operation in transmission and terminal applications.
