Cathode air control valve
Rheinmetall’s innovative solution facilitates precise air and pressure control within fuel cell intake systems, while also allowing for efficient bypass of the humidifier and securing the cathode system. Designed with high resistance to hydrogen and de-ionized water, it is available in various bore diameters, including 38, 40, 48, 60, and 80 mm.
Engineered specifically for use with de-ionized water and hydrogen, the product offers a fail-safe option, configurable as unpowered closed or open. A smart version operates on 12 V with an optional CAN-Bus for 12/24 V systems, while a non-smart actuator is available in both 12 V and 24 V versions. With high excess torque to break through ice, this robust design ensures reliability in demanding conditions.
