Zurn Wilkins model 500XL3 designed for installation on potable water lines to reduce high inlet pressure to a lower outlet pressure. The patented integral venturi enables the valve to have best-in-class flow performance. The high flow capacity makes this device most suitable for Industrial water lines and commercial irrigation systems. The direct-acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion (1" - 2"). The balanced piston design enables the pressure reducing valve to react in a smooth and responsive manner to changes in system flow demand, while at the same time, providing protection from inlet pressure changes. Includes a removable cartridge and corrosion resistant materials.
The Pressure Reducing Valve shall be certified to NSF/ANSI/CAN 61 & 372, consisting of a low lead silicon bronze body and silicon bronze bell housing, and a bolt to adjust the downstream pressure. The bronze bell housing shall be threaded to the body on the 1"-2" sizes or affixed to the body with stainless steel bolts on the 2 1/2" & 3" sizes. The assembly shall be of the balanced piston design and shall reduce pressure in both flow and no-flow conditions with integral venturi for improved flow performance. The assembly shall be accessible for maintenance without having to remove the body from the line. Shall include a removable cartridge and corrosion resistant materials. The Pressure Reducing Valve shall be a ZURN WILKINS Model 500XL3.
