Our manufactured Pinch Valves are very useful for Sludge Control. In Wastewater treatment plants use pinch valves wherever sludge flows need to be controlled. Because pinch valves use the rubber body of the valve itself to control the rate of flow, they keep all working parts out of the sludge. Pinch Valve For Sludge Control provide excellent flow control for hard-to-handle media such as slurries, sludge’s, and dry solids. The sleeve is the only valve part exposed to line fluid, significantly reducing the incidence mechanical component breakdown.
