The Zurn-Wilkins Model 500XL is the workhorse of the Wilkins pressure reducing valve line up. Exhibiting the highest flow rates of the entire Wilkins regulator line makes this device most suitable for industrial water lines and commercial irrigation systems. The low-lead law compliant valve is designed for installation on potable water lines to reduce high inlet pressure to a lower outlet pressure.

Direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion
Balanced piston design enables the regulator 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
All bronze body and bell resists corrosion
High flow rate with minimal fall-off
Valve may be installed in any position and is serviceable in-line
