Spring return = single acting cylinder vs the speeco and most other in that class on up which are double acting.
Single acting - when you let go of the control valve it starts returning as no fluid is being pumped into ram, the spring pulls the ram back forcing the fluid back to the reservoir. Generally the valve does not lock in the extend position.
