I am new to solenoid valves; I know the basic principal, it's just like normal valve but solenoid can be controlled using DC/AC current.
But my question is:
What's the difference between gravity feed solenoid valve and normal solenoid valves?
What are the applications of gravity feed solenoid valves as I have seen many normal solenoid valves used in washing machines and water purifiers.
Normal solenoid valves require some amount of pressure like 3psi for the valve to open. Gravity feed solenoid can allow liquid to flow through at any pressure.
