IRRIGATION VALVE OPEN Momentarily-Energized Pilot Valves for Irrigation Systems

M OMENTARILY-ENERGIZED solenoid valves were developed in both 3- and 4-way configurations. The 3-way model is used as a pilot valve primarily for water-operated valves in surface irrigation systems. The 4-way model can be used with pneumatic operators such as air cylinders. The valves are powered by capacitor discharge with energy supplied from batteries and do not require continuous energization to maintain valve position
