Unidirectional blocking valves are safety devices which can block the cylinder rod when, accidentally, the pressure fails. Bidirectional blocking valves are used to block the cylinder rod when the bistable 5/2 valve that controls it has deenergized pilots. In this case the 5/3 function is obtained.
