Solenoid valves dispense liquids and are for use in gas shutoff, vacuum holding, and tank draining. High-flow valves are for liquid, corrosive, and air/inert gas service. Some valves are for outdoor use, while explosion proof models contain internal explosions without causing an external hazard. Some solenoid valves have a universal valve design so they can be connected in either a normally closed or normally open position. Cryogenic solenoid valves handle cryogenic fluids, including liquid nitrogen, liquid argon, and liquid oxygen. They’re ideal for frozen food and cranial/genetic preservation applications. Solenoid valve coils convert electrical energy into linear motion to control the opening and closing of solenoid valves.
