Hydraulic Answers: Reversing a cylinder

http://hydraulicanswers.blogspot.com/2010/01/reversing-cylinder.html

Saturday, January 9, 2010. Where can i find a valve that changes the direction of a cylinder by stopping flow or presure then restoring flow or presure? I need double action on a single action circut at 70 gpm. thanks. Need a few more details. Could you use a pilot operated valve? Once the cylinder reaches end of stroke the pressure would build and shift the valve. The pressure in the pilot would be trapped with a check valve. January 9, 2010 at 3:49 PM.
