Thermal pressure relief valve
0000-GXX-0334-A0 |
If the engine is running in standby mode without active spraying, the water in the high-pressure pump heats up to 60 °C (140 °F). The thermal pressure relief valve automatically lets the hot water escape from the high-pressure pump so that fresh and cool water can flow into the system.
Pressure/quantity control on the machine
The working pressure and water flow rate can be adjusted on the highpressure pump.
