GENERAL DESCRIPTION. Reliable Pressure Relief: Hayward Pressure Relief Valves protect piping system components from damage due to over pressurization. The valves work by sensing system pressure. When the system pressure exceeds the set pressure, the force of the excess pressure moves the valve piston off its seat to relieve the excess pressure and diverts some of the flow out the discharge port. Easy to Set Pressure: Hayward Pressure Relief Valves can be set by hand, no tools are needed... (read more)Browse Pressure Relief Valves Datasheets for Hayward Flow Control -

How to Select a Pressure Relief Valve
the valve is not doing what it is supposed to do. The first thing to determine is the type of pressure relief valve you are looking for. There are two common types of relief valves. One is the safety or pop off valve that opens completely when the set pressure is reached, diverting all, or almost all...
