The MNRUB water control valve is an alternative to machined brass valves. It has thermoplastic injection molding on the three plastic valve body components and transfer molding on the NSF 61-compliant, chloramine-resistant rubber seals and O-rings. Through the use of finite element analysis, wall thickness is optimized, conserving plastic material while increasing overall valve strength with less weight and reducing total cost. It has a non-corrosive reinforced thermoplastic body. Each welded valve is leak and pressure tested prior to shipping.
