Knife Gate Valve

Lugged and wafer knife gates for slurry and pulp service.

As part of the VTXFLOW gate valve range, the knife gate valve is produced under our certified quality system — from in-house casting and CNC precision machining to 100% pressure and seat-tightness testing before shipment. Our gate valves provide full-bore, low pressure-drop isolation for demanding pipeline services. Available in bolted bonnet and pressure-seal bonnet designs, cast or forged, to API 600, API 602, DIN and GOST standards.

Flexible wedge design reduces thermal binding
OS&Y rising stem with clear open/close indication
Pressure-seal bonnet option seals tighter as pressure rises
Hard-faced seats (13Cr / Stellite) for long service life
