High Pressure Relief Valve | Safety Relief Valve
In addition to the
unloader valve, most major brands of hot water pressure washers such as Hotsy, Landa and Hydrotek, also use secondary safety devices including pop-off valves, rupture disks or thermal relief valves. Although there are a few different designs of safety relief valves, all are designed to do one thing: protect the equipment and the user from damage caused by excessive high pressure or high temperatures. Available in different pressure (PSI) settings, these valves open and release high pressure hot water from the coil or low pressure heated water from the pump head, to eliminate possible damage to the high pressure hoses, trigger guns, heating coil and pressure washer pump.
