2 Solenoid Valves
Inside the head are two solenoid valves, guided electronically by a separate control unit. The two solenoid valves draw from the same oxygen supply. The presence of multiple solenoids assures that you will have access to oxygen even if one of them fails in the closed position. We are using custom made solenoid valve assemblies with duckbill one-way valves that protect the internal mechanisms of the solenoids from any humidity or water that may get in contact with them.
