Self Locking Rod Hydraulic Cylinder

The V270CG are double-acting hydraulic cylinders with a mechanical locking system of the rod in the end stroke position (extended rod), which permits to contrast very high opposite thrusts. Such a solution is widely applicable in the field of plastic injectdie-casting molds, in order to stand the injection pressure on large molding surfaces. The rod is hydraulically unlocked automatically when the piston comes back.
WARNING:
- For a correct functioning the cylinder must always work in the end stroke position (both forward and backward), in order to gantee the locking on one side and to avoid pressure shocks on the piston when it comes back from the other side
- For a firm locking it is necessary to keep the oil in pressure, when pushing, at a minimum of 120 bar-1740 PSI.
- Pay great attention to the traction force, which is considerably lower than the thrust.
