If the air supply device fails and the pressure fluctuates, the signal air pressure supplied to the control valve is automatically maintained at the state just before the pressure fluctuation, and the degree of opening of the control valve is maintained.

  • The signal air pressure can be maintained at the state immediately before the change
  • Can be set to any operating pressure
