Water Pressure Reducing Valve for 1 1/4 Inch Pipes with Stainless Steel Seat

This standard model 1 1/4 inch lead-free brass water pressure reducing valve is designed to lower incoming water pressure, thereby safeguarding plumbing systems and promoting water conservation across commercial, industrial, and residential settings. Maintenance is made straightforward with an assembly that includes a replaceable seat module, an NPT threaded female union inlet, an NPT female outlet, and a bypass feature to manage thermal expansion pressure.

The valve operates within a temperature range of 33 to 180 degrees Fahrenheit (0.5 to 82 degrees Celsius) and is capable of handling pressures up to 300 psi (20.7 bar). Users can adjust the pressure range between 25 and 75 psi (172 to 517 kPa), with a standard factory setting at 50 psi (345 kPa). Research indicates that pressure reducing valves can contribute to significant savings, potentially reducing domestic water heating costs by as much as 30%. Additionally, these valves help prevent water waste and may even lead to lower municipal sewer usage fees.

The valve is constructed from lead-free copper silicon alloy, featuring a stainless steel strainer and corrosion-resistant adjustment and cage screws. It is equipped with a high-temperature diaphragm and a replaceable seat module, ensuring durability and reliability under varying conditions. It also accommodates various end connection options, including PEX, CPVC, and Quick-Connect connections.

Designed with a standard bypass feature, the valve allows water to flow back through it into the main supply when pressures on the outlet side exceed those of the main line due to thermal expansion. This ensures balanced pressure and optimal performance within the plumbing system.
