The valve opens when the primary side pressure exceeds the set value and closes when the pressure falls below the set value. It works using the fluid pressure only, without using any auxiliary power. Against the fluid power pressing up the diaphragm, the valve uses the force of compression spring to press down the diaphragm so as to keep balance. For appropriate flow range, see P.237. . × Pump Primary side pressure, P1 Pressure, P P1 P0 P2 Time, t Pressure setting, PS Pressure, P Pump pressure, P0 Time, t Pump The primary side pressure, PS1, is maintained at a level below the pressure setting, PS, by releasing the pressure exceeding the PS (P0-PS) to the secondary side. Prevents the backward flow due to the siphon phenomenon. MANUAL TYPE What should be filled in the "xxx" section?
