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.
