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. 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 VALVES ARE AVAILABLE

Code:	01.044.4	 Which requires system pressure only.

Code:	01.046.4	 Which requires a constant pilot signal at point X.

		         The pressure can be independent to the pressure at port 1. When 		

		         the pilot signal is removed the valve reverts back to its start position.

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. If the electrical signal is removed or the pilot air 	

		         supply fails the valve reverts back to its start position.

VALVE OPERATION

This is a high-flow device which, by applying a pilot pressure either pneumatic or

electrical to point X, will, for example, extend and retract a double acting cylinder. The

“flip-flop” valve requires two pilot signals for a complete cycle: one momentary signal

to extend the cylinder stroke and one momentary signal to retract. A maintained pilot

signal will generate one half of the cycle. The valve will stay in this position until the

signal is exhausted and then applied again. In the event of pilot pressure failure or

system maintenance a manual override facility is provided.

TWO TYPES OF FLIP-FLOP VALVES ARE AVAILABLE

Code:	10.035.4	 The valve is actuated by applying a pneumatic signal to point X.

		                 The signal pressure can be different to the pressure at port 1.

Code:	01.028.3	 The valve is actuated by an electrical signal with separate pilot air 	

		                 supply which can be different to the pressure at port 1. The pilot air 	

		                 supply must be maintained at point X when the valve is in operation.
