General
These solenoid valves are designed for
gravity-feed systems
. They can be used for draining water and other low viscosity fluids out of tanks, canisters, and containers. These valves are brand new and come with a 6-month warranty. These valves are impossible to find elsewhere.
This is a direct acting valve. The solenoid plunger directly opens and closes the 3/8″ orifice inside the valve. Direct acting valves do not require any differential pressure to operate.
LIMITATIONS:
These
valves are designed for gravity-fed systems and they will
NOT
work with pump or city water pressure. The maximum vertical distance between the top of the fluid surface and valve is 3 feet regardless of tank size. Water column heights over 3 feet create an excessive pressure and the valve may not open. The pressure created by the water column is a function of the height of the water column (the volume of container does NOT affect the pressure).
