Wilkins NR3 Water Pressure Reducing Valve

Specification Sheet

Wilkins NR3 Water Pressure Reducing Valve with Integral By-pass check Valve and Strainer

Designed for installation on potable water lines to reduce high inlet pressure to a lower outlet pressure. The integral strainer makes this device most suitable for residential and commercial
water systems that require frequent cleaning of sediment and debris. The direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion.
The balance 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.
