Bypass Valve Function
The bypass valve has 4 functions:
1. Protect the machine against excess pressure.
2. Relieve the pressure in bypass.
3. Fast conversion to high-pressure.
4. Ensure 0 pressure when the machine is stopped.
Operation:
The water from the pump is led into chamber A of the bypass valve.
From there, the water passes through hole B in piston C and out of the machine.
This leads to a pressure imbalance in piston C, which keeps valve disc D closed to valve seat E.
Bypass:
When water consumption stops (the spray handle is released), pressure increases briefly until safety valve F
opens upon reaching the pressure setting, which should be adjusted to 25-30 bars over working pressure. This
causes the pressure drop in piston C to disappear, and valve disc D moves from valve seat E. The machine is
now running in bypass.
