High-pressure systems can be automated easily and effectively with NOVA SWISS valves with pneumatic actuators. The valve bodies and the sealing system are identical to those of the hand-operated valves, and afford the same advantages.

The very rugged and dependable pneumatic piston actuator is available in two different versions:

  • ATO (air to open), opening with compressed air, i.e. normally closed
  • ATC (air to close), closing with compressed air, i.e. normally open

A mechanical position indicator gives a certain indication as to whether the valve is in the actuated condition or not.

For electronic monitoring and control, if desired, the valves can  be equipped with proximity switches or electrical contacts. Combined visual and electronic position-indicating devices contribute substantially to high operating reliability.

When ordering air-operated valves, the following procedure is recommended: specify the valve you need with the suffix ATO or ATC. For example: NVI-40-4E-ATO.
