KREBS® High-Pressure Knife Gate Slurry Valve

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.

Key benefits

Performance, service life, easy maintenance – all in one universal valve

Safety expand_more

Keep your crews safe with the valve safety features that are offered for all of our valves – reducing hazards during installation and maintenance.

Performance expand_more

The TGH / TGHP Valve’s double-seated design permits bi-directional flow with zero downstream leakage.

Reliable expand_more

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 expand_more

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 expand_more

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

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

In addition to being a perfect solution for tough mining applications, our knife gate slurry valves are invaluable for industrial and flue gas desulphurization processes that require high performance and reliability. It is crucial for a power plant to have reliable valves to keep the process moving so they can meet the demands and emission requirements without downtime.
