A reliable valve for higher-pressure applications
The KREBS® Technequip™ TGH / HP Knife Gate Valves are a true bi-directional slurry knife gate valve built to withstand high pressure conditions. We designed this premium performance valve with massive, replaceable rubber sleeves to seal and withstand the harsh conditions inherent in mining and industrial facilities.
What we offer
Robust bi-directional valves for your higher-pressure applications
Do you need a valve that was built to last under high-pressure conditions? What if you discovered a valve that could last for years, performing faithfully for every shift? Look no further. Our Technequip High-Pressure Knife Gate Valves are the work horse that you have sought for years.
Proven design
The TGH / TGHP Valve is one of very few in the market that has been specifically designed for your most demanding applications. Due to the unique design of the valve, there is no need for a packing gland which reduces maintenance time and eliminates 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.
Reliable operation
Engineered for abrasive slurry applications, Technequip Valves offer field-replaceable wear parts with a drop-in design. The universal frame design allows you to change actuation without removing the valve from service.
Long Life
The heavy-duty valve is designed to keep the valve body and only replace the spare parts (which include the sleeves, retainer flanges and gate) which prolongs the life of the valve. The valve is fully lined which means the slurry never comes in contact with the steel components!
Key benefits
Performance, service life, easy maintenance – all in one universal valve
- Safety
- Keep your crews safe with the valve safety features that are offered for all of our valves – reducing hazards during installation and maintenance.
- Performance
- The TGH / TGHP Valve’s double-seated design permits bi-directional flow with zero downstream leakage.
- Reliable
- 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.
- Long service life
- KREBS Technequip Valves are designed to provide years of reliable performance, without breaking down. Standard dust boots (bellows) and stem covers protect valve stems and actuators. We coat all gates in fluorocarbon to reduce friction between the gate and sleeve.
- Cost-effective
- 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.
Product features
Your ideal high-pressure valve – delivered by design
The Technequip High-Pressure Knife Gate Valve is a heavy-duty, wide-body, slurry knife gate valve designed specifically for highly 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 massive elastomer sleeves. The massive sleeves, which are longer than the valve body, 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.
