Parker’s blocking valves prevents damage to work and equipment in the event of a loss of pressure. Blocking valves which are mounted in pairs on a cylinder lock the piston by simultaneously cutting the supply and exhaust. Functional locks are more precise and rapid when lock out valves are located on the cylinder. Parker’s blocking valves are designed to offer maximum flow capacity and compactness. Manufactured with robust materials, Parker blocking valves are compatible with aggressive environments due to their excellent resistance to salty atmosphere and sparks. A tried and tested sealing and tube gripping technology guarantees performance and reliability.
