Pilot-operated Check Valves

A hydraulic lock protects against the falling of a cylinder. It is designed to maintain pressure in the system in case one of the hydraulic hoses bursts. Hydraulic locks enable the maintenance of cylinders in locked positions, which protects them from falling. If you are looking for a lock for a hydraulic cylinder or motor, send us a photo with a hydraulic diagram or the original part number; we sell locks from well-known Italian manufacturers in both retail and wholesale quantities for machinery manufacturers.
