Hayward® RV Series Pressure Relief Valves

This relief valve can be present to open any desired pressure between 5-75 psi. If line pressure does not reach the set relief pressure, the valve remains closed. When the pressure exceeds the relief value, the valve opens and diverts the flow. It remains open until the pressure drops back to the desired value, then closes.
