SERIES A VALVES
Manual and Mechanically Operated
Available with either hand, foot or palm button actuators, manually operated
Series A valves can be used directly as power valves to control air actuators or
indirectly to operate larger pilot operated hydraulic or pneumatic valves.
Hand or foot operated models are available with spring offset or with optional two
position detent.
Three position, spring centered or detented, open or closed center hand valves are
available as special assemblies. Consult factory.
Actuating force of palm button is only 2 lbs.
Mechanically Operated
The mechanically operated Series A is a ball cam operated valve. It can be used as
a power valve to control air actuators or to control larger pilot operated hydraulic or
pneumatic valves.
• Stroke: .250”
• Shifting force: 3.85 lbs. minimum

Multiple Station Manifolds
Series A valves may be manifold mounted in a flexible arrangement which allows
the stacking of any number of valves in any combination of actuators.
With multiple manifold assembly, only one inlet connection is required for the entire
manifold assembly.
The exhaust port on the manifold is also common to all valves in the assembly.
Both inlet and exhaust ports are 1/2 NPT. Cylinder ports are available in either 1/4
or 3/8 NPT. All manifold bases are provided with side and bottom cylinder ports and
are shipped with the bottom cylinder ports plugged unless otherwise specified.
