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.

Q:I have a Wilkins NR3 would like to know what the replacement water pressure regulator valve is
A:The NR3XL would be the replacement series. The connection size was not specified but that would be the series that replaces the NR3.
Q:is this model identical or compatible to Model BR 4 A Zurn Wilkins ?
A:Yes model NR3XL is the direct replacement for the older model BR4.
Q:What is the range on this? We need 2.5-75.
A:the PSI range is 15-75, I do not see any that will go that low.
Q:What is the pressure set for by the factory?
A:This Pressure Reducing Valve is factory preset for 50 PSI. There is an adjustment bolt on the unit. Multiple installations are recommended for wide demand variations or where the desired pressure reduction is more than 4 to 1 (ie: 200 psi inlet reduced to 50 psi outlet). CAUTION: Anytime a reducing valve is adjusted, a pressure gauge must be used downstream to verifycorrect pressure setting. Do not bottom the adjustment bolt on bell housing.
