Knife Gate Valve

Name: Knife Gate Valve
Brand: VTXFLOW

Lugged and wafer knife gates for slurry and pulp service.

Gate Valve Series

Knife Gate Valve

A sharpened gate edge cuts through pulp, slurry and fibrous media that would jam ordinary gate valves. Lug or wafer bodies keep face-to-face short and weight low for mining, paper and wastewater plants.

As part of the VTXFLOW gate valve range, every 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, with EN 10204 3.1 material certificates supplied.

Sharpened 304/316 gate cuts fibrous media
Wafer / lug short pattern saves space
Replaceable resilient or metal seats
Handwheel, chainwheel, pneumatic or electric operation
