Slurry Ball Check Valves | Upwey MAXI-Check

High pressure, abrasive, slurry handling valves from Upwey:

Mining and mineral processing – ball check slurry valve offers pump protection and non return on dewatering pump sets, tailings lines and cyclone feed pumps. Most common uses are for dewatering and slurry or tailings

General irrigation, water, wastewater and sewage treatment plants – commonly found in pumps sets, and used as foot valves, on water and effluent intakes.

Construction – valves commonly used as a foot valve in dewatering pump sets as well as a non return valve for larger gravel/grit waste extraction pump sets.

Power generation:

Ash water pump sets, where the abrasive ash content in the water erodes standard swing check valves within short timeframes, the ash slurry valves from Upwey Valve & Engineering offer the best solution, as well as on pump sets for raw water/cooling water intake.

Pulp and paper industries, chemical and soda ash installations – pump protection, foot valves and non return functions where larger particle size and/or corrosive nature of the medium being pumped can pose problems.
