Pressure reducing valve 50 psi

This Watts valve reduces incoming water pressure to a preset 50 psi and can be adjusted between 25 and 75 psi. It fits 1 1/2 inch FNPT connections and is built from lead-free brass. The unit meets ASSE 1003, CSA B356 and IAPMO standards. It is not suited for systems requiring a built-in strainer.

Thermal and pressure limits

The brass body withstands a maximum temperature of 160 degrees and a maximum working pressure of 300 psi. As a purely mechanical device it generates no operational noise and draws no electrical power. Performance remains stable within the stated adjustment range under normal supply conditions.

Lead-free brass construction daily use

The lead-free brass construction resists corrosion and complies with current drinking-water regulations. FNPT x FNPT threads allow direct installation on threaded pipe without extra adapters. Overall height is 11-15/16 inches and length is 8-3/4 inches, so verify clearance before fitting. No strainer is included, so upstream filtration must be provided separately.

Questions about this item

How do I install the 1 1/2 in. FNPT x FNPT valve correctly, and which step do people often miss?

Thread the valve onto the 1 1/2 in. FNPT connections using pipe sealant on male threads, orient the body so the arrow matches flow direction, then tighten. The step most often missed is verifying the arrow direction before final tightening.

What maintenance will the lead-free brass body and internal seat need over time?

The valve has no strainer, so debris can reach the seat. Flush the line before start-up and inspect the seat annually for scale or wear; replace the seat or cartridge if pressure creep appears.

At what point does the 160 max temp limit become the governing factor during sustained use?

The valve is rated to 160 max temp. If the supply temperature reaches or exceeds 160, the temperature limit governs before the 300 psi pressure rating, and the valve must be derated or protected.
