The 2" 500XLHLR Pressure Reducing Valve works effectively for industrial water lines and commercial irrigation systems with high-flow rate capacity and low falloff. It includes a spring range of 10 psi to 125 psi, factory set at 50 psi. The balanced piston design enables the regulator to respond seamlessly to changes in the system flow demand, ultimately providing vital protection from inlet pressure changes. The direct-acting integral bypass design prevents buildup of excessive system pressure caused by thermal expansion. The all-bronze body and threaded bell provide superior corrosion resistance and easy access to the internal system. You will save valuable installation time and labor costs.
