The function of pressure protection valve for hot water is when the pressure in the container exceeds a certain value, the pressure safety valve opens the valve automatically depending on the pressure of the medium itself, and the pressure protection valve quickly excludes a certain amount of medium. However, when the pressure in the container drops to the allowable value, the pressure safety valve automatically closes again.
