Our proven TG knife gate valve is now available in a wafer valve!


Our wafer knife gate valve is a space-saving option for medium to heavy duty applications. We designed it in response to the industry's need for valves that are able to isolate flow in demanding conditions requiring smaller face-to-face flange dimensions.


Our cost-effective knife gate valve for reliable isolation anywhere

TGW Wafer style knife gate valve


This narrow-body valve is simple to install, featuring the same face-to-face dimensions that are typically found throughout the industry.

Offered in many different actuator options including, air cylinder (to include option for manual over-ride, low air supply and spring return), handwheel, bevel gear, hydraulic, and electric


Our Technequip knife gate valve line offers advanced standard features!

The TGW is our Wafer Style Slurry Knife Gate Valve designed specifically for lighter duty in abrasive applications. It features a full-port, open-body design, which allows the gate to create a path for solids to exit through the bottom of the valve as it passes between the elastomer sleeves reducing the possibility of jamming. The sleeves compress to provide a 100% bubble-tight seal, resulting in zero downstream leakage when the valve is in the fully open or the fully closed position.

Flush ports

We have added flush ports to the valve housing to assist in keeping the housing area free of build-up.

Wiper / Secondary seal

A newly designed wiper assembly completely surrounds the gate assisting in redirecting the solids out the bottom cavity of the housing during actuation.  For easy maintenance, the wiper blade is field-replaceable without removing the valve from its installed location.

Grease Ports

The grease ports have been strategically positioned to aide in easy grease distribution.
