solenoid valve minimum pressure requirement

Post by mistered »

According to the specifications the solenoid actuated 1/2" plastic water valve requires 3 psi minimum pressure to actuate properly. In an application involving a passive (non-pumping) water transfer system would the static weight of the water in a container holding say 30 gallons be sufficient to let the valve work properly? I don't believe the volume is the critical parameter but the actual height of the water column. There would be about 2 1/2 to 3 feet of column height.

Thank you for any assistance.

3 feet of water is going to give you a pressure of about 1.3 psi. You would need about 7' to get 3 psi.
