Singer Valve - Model 106/206-RPS-L&H -Surge Anticipating Relief Valve
The 106-RPS-L&H and 206-RPS-L&H anticipating surge relief valves are based on the 106-PG or 206-PG main valve. The valve is mounted in a tee, downstream of the pump check valve(s). It is designed to anticipate surges to avoid the severe water hammer often associated with power failure surges.
The RPS-L&H pilot system is comprised of two pilots, the 81-RP and the 82-PR. Both pilots sense pressure through a connection to the header pipe. The 81-RP high pressure pilot opens the valve to relieve excess pressure. The model 82-PR low pressure pilot opens quickly on below normal pressures prior to the return of a surge wave, initiating the opening of the main valve in anticipation of the high pressure wave’s arrival.
