A pressure relief valve is a valve used to control or limit the pressure in a system, which can build up due to a process upset, instrument or equipment failure. The pressure is relieved by allowing the fluid to escape through the valve and then through an auxillary passage out of the system back into the supply tank.
The inlet is a 3/4" NPT male thread and the outlet is a 3/4" NPT female thread. The maximum working temperature is 60 degrees celcius.
The wetted parts are: Nylon body and valve; Brass valve stem; Powder Coated Steel spring.
