Flip-flop
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 10.018.3 The valve is actuated by an electrical signal.
