The 2'''' 500XLYSBR Pressure Reducing Valve includes a wye strainer for added debris protection, and is best suited for industrial water lines and commercial irrigation systems with high flow rate capacity and low fall-off. It includes a spring range of 75 psi to 125 psi, factory set at 85 psi. 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 direct acting integral bypass design prevents buildup of excessive system pressure caused by thermal expansion, and the all bronze body and threaded bell provide superior corrosion-resistance and easy access to the internal system, saving you valuable time and labor costs.
