Sun solenoid cartridges are offered in pilot flow, full flow, and high capacity versions. Pilot flows are available in 2-way and 3-way versions. Full flow versions are available in 2-way, 3-way, 4-way and 6-way functions. Our high capacity solenoids are 2-way, normally open or normally closed cartridges with flow from 1 to 2 or 2 to 1. A wide selection of override options are available, along with coil voltages and terminations. Most of our solenoid valves can be fitted with weatherized and explosion proof coils.
