PNEUMATIC VALVES
DESCRIPTION
The pneumatically operated Series 3 and Series 4 valves have been
designed with three different methods of return. A pneumatic signal,
mechanical spring or differential pneumatic return. This is due to
the type of design consisting of a balanced spool, which means that it can
be used for a wide range of applications.
