The larger section in the upper chamber compared to the fluid passage section causes the valve to remain closed when there is upstream fluid pressure, as the 3-way solenoid connects the pressure from the pump to the upper chamber of the valve. By opening the drain of the upper chamber, either automatically with a signal from the selector valve or via the solenoid's manual selector, fluid is prevented from entering the chamber, and therefore the fluid in the line overcomes the membrane, causing the valve to open.\u003c\/p\u003e\n\u003ch4\u003eDocumentation:\u003c\/h4\u003e\n\u003cp\u003e\u003ca
