Check valve in the middle.

Check valve in the middle.

Allows flow from left to right, and blocks flow from right to left.

what would a common use be for this ? i was told its rare and comes in handy if u use 2 attachments ? i dont get it

That valve will allow oil to go one direction but not the other direction.

Yes, usually this arrangement is for mounting directly on a hyd motor to prevent the motor from reversing direction

G'day they are commonly used as stated in a motor circuit and are there to allow the motor to run down when you release the control lever so the pump doesn't have a sudden stop much nicer on the motor,seals and lines

ty so if i understand -it helps to prevent the hydrolic "hammer" with an abrupt stop and would be good to install directly on my hydrolic pump ? and so everything would be fed from it ? just confused on where it would install on the hydrolic system on a case/ingersoll 6018 -

Jon hit it. They are tipically used for allowing a motor to spin down with the rotating mass on something like a snowblower. It allows the motor to turn into a pump for a short time so it does not "lock" in place when the control valve is put into the center position. A motor spool in the control valve does basically the same thing but will allow a load to drop in the center pos. so a check valve is put in place when using a cylinder spool. That serves no purpose on a pump but goes on the implement most of the time. Pretty cool, you can still see the check indicator on the side! CJ
