The 106-RPS, 206-RPS or 306-RPS pressure sustaining valves are based on the model 106-PG, 206-PG or 306-PG main valve.
The 81-RP pilot senses the upstream pressure through a connection to the valve inlet. The valve and pilot remain closed until the inlet pressure exceeds the pilot setting.
Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm.
Should the upstream pressure fall 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
