Overflow valve with two pressure switches

• While reducing the water supply at the pump head or with the Servopress - regulation the overflow valve opens and part of the water flows back to the pump suck side.
• If the hand-spray gun is closed, so that the whole water flows back to the pump suck side, the pressure switch at the overflow valve shuts down the pump.
• If the hand spray gun is opened, the pressure switch on the cylinder head turns the pump back on.

The overflow valve is set by the manufacturer and sealed. Setting only by customer service.

Safety valve

• The safety valve opens, when the overflow valve resp. the pressure switch is broken.

The safety valve is set by the manufacturer and sealed. Setting only by customer service.
