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 off the supply and
exhaust. Functional locks are more precise and rapid when blocking
valves are located on the cylinder: the volume of air in the pipework no
longer needs to be taken into consideration.
