The 3'''' 500XLFC Pressure Reducing Valve is utilized in both industrial water lines and commercial irrigation applications requiring 150 class flanged connections, providing exceptional high flow rate capacity and low fall-off. The balanced design of the piston enables the regulator to react in a responsive, smooth manner to changes in the system flow demand, providing vital protection from inlet pressure changes. The all bronze body and threaded bell, plus the stainless steel internals, offer superior corrosion-resistance and easy access to the internal system, saving you valuable time and labor costs.
