Fast Acting Relief Valve
This fast acting, surge prevention, pressure relief valve avoids the damaging effects of water hammer in pipeline networks.
It is designed to prevent pressure from rising above a pre-set value through its capacity to discharge an exces volume of water through its flanged outlet.
