Air Clamp, Controlled Force. (Spool Valve
Shown)
Cylinder clamping force can be controlled by a separate regu-
lator when used with a dual pressure valve. (Port 1 becomes
exhaust.)
Interlock Circuit. (Spool Valves Shown)
The cylinders can be either air spring or spring return. The
cylinders are interlocked with the pressure extending one
cylinder, disabling the other cylinder circuit. One cannot be
extended as long as pressure is applied to the other
*Regulator relief flow must be sufficient to accommodate the
cylinder speed. Flow controls will allow variations of cylinder
extension speed.
