Parker M315-5201 Pressure Reducing Valve 240 Psi

Product Description

The PARKER M315-5201 is a proportional control pressure reducing valve rated to a maximum of 240 psi. It is engineered to reduce incoming line pressure to a controlled range of 8 to 20 psi, protecting downstream equipment and maintaining consistent system performance. The valve body is constructed from bronze and features a 1-1/4 inch Female NPT connection for straightforward integration into existing piping systems. Licensed plumbers and pipefitters install this type of valve in commercial and industrial fluid systems where precise pressure management is required. The unit weighs 37 pounds and is rated for operating temperatures from -40 degrees F to 400 degrees F.

This pressure reducing valve is suited for commercial and industrial plumbing and process piping applications where high inlet pressures must be stepped down to a stable, lower working range. The wide temperature rating makes it appropriate for demanding environments including steam-adjacent or high-heat process systems. Its bronze body construction provides durability in potable and non-potable water service as well as compatible fluid systems. The 1-1/4 inch Female NPT connection accommodates standard threaded pipe runs without the need for adapters in most configurations.

• Bronze body construction for corrosion resistance and durability
• 1-1/4 inch Female NPT end connection for standard threaded pipe compatibility
• Wide operating temperature range: -40 degrees F to 400 degrees F
• Proportional control design for stable, responsive pressure regulation

Compatibility

Designed as an OEM-style replacement or direct installation option for commercial and industrial proportional control pressure reducing valve applications using 1-1/4 inch Female NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ANSI standards. Shut off the supply line and relieve all system pressure before removing an existing valve or installing this unit. Use appropriate thread sealant rated for the fluid type and temperature range of the system. Do not exceed the valve maximum pressure or temperature ratings during operation or testing.
