A slab gate valve is a linear-motion isolation valve featuring a flat, parallel-faced gate designed for low-torque, high-pressure shutoff in demanding oil and gas transport systems. Unlike wedge gate valves, a slab gate valve relies on line pressure to press the floating gate against the downstream seat, allowing closing to be controlled via automated travel switches rather than torque switches. Because the flat gate remains in continuous sliding contact with the seat rings, it wipes away debris and prevents suspended solids from fouling the sealing surfaces. Procurement networks and pipeline contractors can lower infrastructure costs by importing API 6D certified slab gate valves directly from top-tier manufacturers in China via our global B2B digital marketplace.
