Quick-Set Pressure-Regulating Valves for Water

For Use With: Water
Temperature Range: See Table
Specifications Met:
Brass Body Valves: CSA Certified
Stainless Steel Body Valves: ASSE 1003 Listed, CAN/CSA-B356, CSA Certified, IAPMO Listed

Change outlet pressure without using a gauge—turn the dial to adjust the outlet pressure in 5 or 10 psi increments. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. They also have an internal strainer to trap debris. Union fittings on both ends of the valves disassemble for easy valve installation and removal. All of these valves meet Canadian safety standards for pressure-reducing valves. Some also meet American and international plumbing safety and performance standards.

Stainless steel valves resist corrosion better than brass valves.

Pressure-Regulating Valves for Drinking Water

Valve

Valve With Union Fitting

For Use With: Drinking Water
Temperature Range: 33° to 140° F

These valves meet NSF/ANSI 61 for use in drinking water systems. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. All valves have a gauge port. An internal strainer traps debris. Body is bronze for durability and a long service life.

Valves with union fitting disassemble for easy installation and removal.
