106/206 RPS – Singer Pressure Sustaining Valve
The 106/206 RPS Pressure Sustaining Valve is mounted in the main water pipeline. The valve operates by sensing the upstream pressure through a sensing port in the valve inlet. The Type 81-RP Pilot Valve then modulates the main diaphragm to maintain the pre-determined pressure set point. Under normal flowing conditions, the pilot reacts to small changes in the upstream pressure to control the valve position by modulating the pressure above the diaphragm. In the event of the upstream pressure falling below the set-point, the valve will close or modulate to ensure that the set-point is maintained.
- Ensures minimum upstream pressure for critical use
- Closes if inlet pressure drops below set-point
- Easily adjustable pressure setting
- Accurately maintains pressure to set-point
