Solenoid Valves for Express Car Washes

Solenoid valves play an important role in the control of many functions in an express car wash tunnel. When solenoids are activated by an electric current, they either open or close fluid lines, depending on the application. Normally closed solenoid valves are closed by default, so the line only opens when the valve is activated, and fluid begins to flow. Conversely, normally open solenoid valves are open by default until the valve is activated and closes the fluid line.
