106 / 206-RPS Pressure Differential Sustaining Valve

Features

  • Maintains a minimum differential pressure
  • Easily adjustable differential pressure setting
  • Valve closes drip-tight when the pressure differential is less than the pilot setting
  • Based on 106-PG and 206-PG main valves
  • Uses 2 sensing connections to establish a steady differential pressure despite changes in the system pressure and flow

Specs

  • The valve shall be a Singer Valve model 106-RPS-D / 206-RPS-D, 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 81-RPD Differential Pilot spring range shall be “___ to ___” psi / bar, with set-point preset at Singer Valve to “___” psi / bar. Assembly shall be according to Schematic A-0428B.
  • The valve will automatically open when the pressure differential across the valve exceeds the pilot set-point. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm. The pilot setting establishes a differential pressure, which is held relatively constant despite changes in system pressure or flow.
  • Refer to Main Valve section, see page 11, 106-PG (or 206-PG) for detailed information pertaining to valve sizes and materials, selection criteria and specifications.
  • Refer to Pilot and Accessories section, see page 249, Model 81-RPD Differential Pressure Pilot for detailed information pertaining to materials and specifications.
