Description

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.
Max. working pressure: 10 bar
Ambient and fluid temperature: -20 +180 °C
