API 600 Industrial Gate Valve
KBN Engineers manufactures high-integrity Cast Steel Gate Valves conforming strictly to API 600, ASME B16.34, and BS 1414 standards. Designed for full-flow isolation with minimum resistance, the gate rises completely into the bonnet neck to provide an unobstructed straight-through flow passage.
Constructed in WCB carbon steel or CF8/CF8M stainless steel with an Outside Screw & Yoke (OS&Y) bolted bonnet, rising stem, and flexible wedge, every valve is individually hydrostatically shell tested up to 425 Psi (30 Kg/cm²) according to API 598.

Full Port Unrestricted Flow
Straight-through full diameter port generates negligible turbulence and minimal head loss across pumping systems.
Tested to 425 Psi Shell Test
High-grade WCB / CF8M pressure containment certified according to API 598 hydrostatic protocols.
Flexible Wedge Sealing
Accommodates thermal piping expansion and contraction without sticking or galling inside valve seats.
