Pressure Reducing

106-PR-10159

UL Pressure Reducing Valve

  • UL approved for fire extinguishing systems
  • Reliable diaphragm actuated
  • Hydraulically operated design
  • Stainless steel fasteners
  • ANSI class 150 and 300 flanges
  • Heat-fused red epoxy coating
  • Available in globe style

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-PR-8702A

ULC Pressure Reducing Valve

  • ULC approved for fire extinguishing systems
  • Reliable diaphragm actuated
  • Hydraulically operated design
  • Stainless steel fasteners
  • Class 150 and 300 flanges
  • Heat-fused red epoxy coating
  • Available in globe and angle style

The 106-PR-8702A, which is ULC 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 or A106PG control valves and are available in a complete range of sizes from 1 in / 25 mm to 8 in / 200 mm. In typical pressure reducing applications, the globe style 106-PR-8702A is often the preferred valve style.

  • The valve shall be a Singer Valve model 106-PR-8702A, size “_____”, ANSI Class 150 (ANSI 300, ANSI flanges drilled to ISO PN 10 / 16 / 25 or 40) pressure rating/ flange standard, globe (angle), style valve. The Model 160 Pressure Reducing Pilot (Normally Open Pilot) spring range shall be “___ to ___” psi / bar, with set point preset at factory to “___” psi / bar. Assembly shall be according to Schematic A-8702A.
  • The valve shall maintain relatively accurate control of the downstream pressure regardless of fluctuation in flow or upstream pressure.
  • Refer to Main Valve section, see page 11, 106-PG, for detailed information pertaining to valve sizes and materials, selection criteria and specifications.
  • Refer to Pilot and Accessories section, page 249,Model 160 Pressure Reducing Pilot (Normally Open Pilot) and Model 26 Flow Stabilizer for detailed information pertaining to materials and specifications.
  • Note: Valve must be ULC approved.
