Working Principle
Fluid enters the pressure return valve from the inlet and is blocked by the diaphragm piston, thereby exerting an upward pressure on the diaphragm piston. When the pressure is sufficient, the fluid lifts the diaphragm to form a passage, and the fluid flows out of the pressure return valve from the outlet; if the fluid pressure is insufficient, it will cause a pressure build-up at the inlet.Pressure RisesUntil reachedRated Pressure（Rated PressureThe system can automatically adjust, lifting the diaphragm piston to form a passage.
