OnC AirValve

OnC AirValve

Withstand the toughest conditions

To produce linear movement in order to operate the valve, OnC AirValve uses air pressure. Customers profit from a high air flow rate and application possibilities even under harsh conditions.

With OnC AirValve, Voith supplies different on-off valves with either built-on Namur solenoid valves or solenoid valve blocks. They contain 8 or 16 solenoid valves, which are normally integrated into cabinets. For the tubing between the solenoid valves and the process valve actuators, Voith tube bundles with welding beads protection are recommended as they contain two tubes in one. The Namur interface of the process valves pneumatic actuator eases direct mounting of the solenoid valve onto the actuator. Thus, installation costs are decreased and pneumatic and electric installation simplified. For all rotary actuators the switchbox VS500 is the perfect addition to connect the solenoid coil cable.
