Blocking
valves G 1/8" ÷ G 1/2"
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.
