- Long service life
The same proven design of our TG is now available in a wafer style!
Our cost-effective solution for reliable isolation anywhere
Do you need a valve that is cost-effective and yet still delivers the same KREBS Technequip™ quality? Look no further. Our TGW Wafer Style Knife Gate Valves are the premium valves you have sought for years.
This narrow-body valve is simple to install, featuring the same face-to-face dimensions that are typically found throughout the industry for wafer valves of the same design.
The TGW series Knife Gate Valve is bi-directional and best suited for the abrasive applications that are often encountered in the mining and industrial industries. It is one of very few in the market that has been specifically designed for your most demanding applications.
Its replaceable elastomer sleeves offer the latest technology in a reliable sealing solution.
The sleeves fully line the body of the valve ensuring no steel components come in contact with the slurry.
With no packing gland, we also have eliminated the associated actuation issues caused by slurry build-up and dewatering in and around the packing gland. It also allows the gate to eject material out of the bottom during actuation, so you can be sure of full gate closure and a reliable seal. The gate is fully out of the pipeline when open. This minimises pressure drop across the valve.
The heavy duty design allows you to replace the spare parts and keep the valve body, prolonging the overall wear life of the valve.
Long service life and easy maintenance - in one space-saving valve!
- TGW Valves are able to isolate flow in demanding conditions where space is limited, requiring smaller face-to-face flange dimensions.
- Keep your crews safe with the valve safety features that are offered for all of our valves - reducing hazards during installation and maintenance.
- Keep your operation running smoothly and keep your valve in service longer with our replaceable wear sleeves and universal yoke (frame) design. Longer wear life and faster maintenance means less downtime.
- Longer service life
- KREBS Technequip Valves are designed to provide years of reliable performance, without breaking down. Many upgrades are supplied as standard features!
Consider your return-on-investment in reduced downtime for replacement and maintenance. In particular, the longer your valves last, the lower their cost of ownership, as you enjoy years of dependable service.
The newest addition to our Technequip line offers upgraded 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.
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.
The grease ports have been strategically positioned to aide in easy grease distribution.
