Thermal safety valve set pressure.

Pressure relief valve is the term used to describe relief device on a. Pressure safety valve is the term used to describe relief device on a compressible fluid or gas filled vessel. Thermal relief valves are a must have for pressure washers when the water is supplied by a garden type water hose.

The set pressure of the valve must not exceed the maximum allowable working pressure mawp of the boiler or other vessel. This is referred to as a closed loop by pass. Safety valves are primarily used with compressible gases and in particular for steam and air services. These relief valves are specifically designed for thermal safety relief applications and lng liquid containers.

When the set pressure of the valve is reached the valve opens almost fully. When the operator releases the trigger the pump s unloader diverts the water back to the inlet side of the pump. When an overpressure is detected the disc of the valve opens so it can discharge the fluid restore normal pressure conditions in the piping system. What this means is that the valve must open at or below the mawp of the equipment.

Safety valve a pressure relief valve actuated by inlet static pressure and characterised by rapid opening or pop action. For such a valve the opening is sudden. A safety valve opens automatically and at once anytime the pressure of the fluid passing through the valve goes above a set pressure in bars or psi.
