Air Clamp and Work Cylinder Controlled by
One Valve.
(Spool Valve Shown)
The flow control delays the extension of the work cylinder until
the clamp cylinder is in place. The clamp cylinder force is limited
to the work cylinder load until the work cylinder is fully extended.
When the manual valve is reset, the work cylinder will return be-
fore the clamp cylinder is released.
Air Clamp and Work Cylinder Controlled by
Two Valves.
(Poppet Valves Shown)
The solenoid valves are energized at the same time. The clamp
cylinder is extended and goes to full clamp force. The work cylin-
der extension rate is controlled by the flow control. The advantage
of this circuit is that separate control of the two valves is possible
if desired.
