Turning off electric valve after cylinder is extended

[ParkerFly]

I'm working with an electric valve (Parker BV-18 I believe is the #). What I'm wanting to use is for is a microswitch will be flipped which will trigger it to extend a cylinder. Once that cylinder is extended, is there any way to trigger something that will stop the power? I'm concerned about the valve going into bypass and being hard on the hydraulic belt because it could potentially in this situation for several seconds multiple times.
I've seen manual valves that kicked back to neutral I guess once a certain pressure was reached, but never an electric. Any ideas? Thanks,

Justin

You will have to build a simple circuit to do that...Like a latching relay to engage the valve and the microswitch would release the relay.

All you need is a basic switch, that will cut power when the rod hits a set point. You can change the set point at any time. No power is essentially neutral. If you wanted the rod to extend and retract, you would put a reversing switch in place. A relay setup could do all that if there was something at the max extended position. One push on the switch, and the rod would extend, and either shut off the solenoid or reverse and return to the retract position, and cut off power. .

How are you going to retract the cylinder?
I have a auto cycle setup that have the relay circuit that you need for this...It was made for a guy setting up auto cycle for a press
