4.6. Throttling function
The operating speed of the valve actuator can be varied or
reduced. This may be necessary to slacken the actuation of the
valve in order to prevent pressure hammers in the piping
installation. For this purpose, the supply and exhaust air of the
first solenoid valve can be adjusted via the throttling screws
respectively allocated in the interface of the solenoid valve.
By turning the screws in anticlockwise direction, the inlet or
outlet air is throttled.
