106-PR-10159 PRESSURE REDUCING (RESIZE).

106-PR-10159 UL Pressure Reducing Valve

The 106-PR-10159, which is UL labelled and listed, is ideal for automatically reducing a higher inlet pressure to a steady lower discharge pressure, regardless of fluctuations in flow or inlet pressure.The valves are based on the 106-PG control valves and are available in a complete range of sizes from 2 in / 50 mm to 8 in / 200 mm. In typical pressure reducing applications, the globe style 106-PR-10159 is often the preferred valve style.

106-RPS-8700 UL / FM Pressure Relief Valve

The 106-RPS-8700 pressure relief valve, which is UL / FM labelled and listed, automatically relieves excess pressure in the fire protection system to discharge. The RPS series valves will also automatically modulate to relieve excess pump capacity during pump start up and shut down, allowing the pump to operate without causing surges. These relief valves are based on the 106-PG or A106-PG main valves and come in complete range of sizes from 2 1/2 in / 65 mm to 8 in / 200 mm. In typical pressure relief application, the angle style A106-RPS-8700 is often the preferred selection.

Model 18-FR Pressure Relief Valve

The 18-FR is a remote sensing, high capacity, spring and diaphragm operated, normally closed valve. The inner valve is held closed by the spring. When the sensed pressure increases above the spring setting, the valve opens.

​

  • The normally closed valve shall be of stainless steel construction with a spring to adjust the opening pressure.

  • The inner valve shall be of stainless steel 316 construction and the inner valve shall have EPDM resilient compound for seating.

  • A separate port will sense pressure to open the valve when system pressure exceeds the valve set-point.

  • Maximum working temperature: 180° F / 82° C

  • Maximum working pressure: 400 psi / 27.6 bar
