    Diaphragm pumps always discharge the suctioned liquid. Therefore, if the discharge-side piping is blocked, while the pump is operating, the pressure will continue to increase until something breaks. A relief valve automatically releases excessive pressure that occurs in the discharge-side piping due to issues such as clogged foreign matter and valve closures. In this way, relief valves prevent accidents such as pump and piping …
