A hydraulic cylinder is disclosed. The hydraulic cylinder may have a tube, and a piston disposed within the tube and having a bore passing through the piston. The hydraulic cylinder may also have a valve element disposed within the bore and having a length shorter than a length of the bore. The valve element may be mechanically movable to allow fluid flow through the bore, and hydraulically movable to inhibit fluid flow through the bore.
