Knife Gate Valves - Mining and Slurries

As specialists in WARMAN pumps we are also proud to offer the WEIR range of knife gate valves, including the USA made Delta range and more cost effective ISOgate range. The range also includes pneumatic pinch valves, mining quality check vales (non return) and the Autoball AB3 valve.

There are a number of processes within a mine site which require specialised valves designed to handle highly abrasive environments.

Delta Industrial™ knife gate valves are ideal for many of these demanding processes.

Mill circuit

The mill circuit presents a number of issues when selecting a valve. Large particle sizes, high percentages of solids, and high specific gravity make selecting the correct valve critical to achieving the least possible downtime. We can customise our Delta Industrial™ valves to provide optimal performance in any part of the mill circuit. The Delta Industrial™ 15 series and Centre, Block and Bleed (CBB) valves provide outstanding isolation performance, with zero leakage shut-off and no discharge to the nvironment during operation.

Tailings and slurry transport

Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. The pressure in these lines can exceed 50bar (725psi), necessitating engineered valve solutions for safe and reliable operation. We have developed the Delta Industrial™ 60 series valves for such applications, being capable of handling 102bar (1480psi).
