Oscillating valve
Valve operation
It is a high-flow device which allows a double acting cylinder or analogue pneumatic equipment to automatically extend and retract without the need for limit switches. The frequency of the phases is set through the two adjusting screws which are placed at the end of the oscillating valve and protected by a cover. One screw is to set the retract dwell time and the other is to set the extend dwell time. On request the adjusting screws can be mounted on a panel in remote position.
When system pressure is applied or removed the valve automatically moves to the start position ensuring no device is left in a semi-actuated position.
Three types of oscillating valve are available:
code 01.044.4 Which requires system pressure only.
code 01.046.4 Which requires a constant pilot signal at point X. This pressure can be independent to the pressure at port 1.
code 01.008.3 Oscillations are activated by an electrical signal with separate air supply. It is therefore necessary to apply to point X a pilot pressure (that can be of a different value to port 1) and an electrical signal at the solenoid pilot.
