Minnesota Rubber Produces Moulded Water Valve
Minnesota Rubber and Plastics has provided a moulded valve with precise internal flow paths for the redesign of a machined brass water control valve. Previously, the brass valve required costly secondary machining to create the complex flow paths. The project involved a dual-tank water-treatment control valve that provides a continuous supply of softened water from one tank while a second tank is being regenerated. The control valve is critical to reliable water softener function by regulating flow rates for resin regeneration, rinsing and flushing of the water softener. The valve services both resin tanks in the water softener. The design challenge for Minnesota Rubber and Plastics was to provide a moulded water control valve equal to or better than the existing brass water control valve without sacrificing water flow rates while meeting regulatory requirements for structural performance and water purity. Price targets, material and energy savings with just-in-time delivery were ...
