106/206 RPS-D - Singer Differential Pressure Sustaining Valve

The Singer 106/206 RPS-D Differential Pressure Sustaining Valve modulates to maintain a maximum pressure differential between two sensing connections. It is installed in-line and maintains the head on a pump, or when installed in parallel, limits pressure differentials across devices.The RPS-D uses the Type 81-RPD pilot valve and has two sensing connections. The valve and pilot remain closed until the difference between the two pressures exceeds the pilot setting. Under normal 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 that is held relatively steady despite changes in system pressure or flow.
  • Maintains a minimum differential pressure
  • Easily adjustable differential pressure setting
  • Valve closes drip-tight when the pressure differential is less than the pilot setting
