Designed to anticipate surges to avoid the severe water hammer

  • Description
  • Additional information


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.

  • Protects against power failure surges or pressure waves caused by velocity changes
  • Quick opening relief
  • Easily adjustable pressure setting
  • No electrical services required
