Auxiliary Valves

Stop valves mounted on the cylinder inlets allow a flow of air only in the presence of a pneumatic pilot.

Unidirectional and bidirectional versions are available.

This item is mainly used as a safety valve. When pressure drops in the pneumatic pilot, all cylinder movement is halted

The compressed air quick-fit coupling by Metal Work allows quick
replacement of pneumatic equipment (drills, milling machines, screwers
and actuators in general) without having to set the line pressure to zero
each time. Rapid tool changeover can be easily obtained by fitting
a female body on the branch under pressure and the male coupling
on the actuator. The presence of a female coupling with a safety valve on
the branch under pressure prevents air dispersion during disconnection.
