THREE PILOT RELEASE METHODS
ADJUSTMENTS
For most pilot release applications, set the Feed Pitch
approximately .005" (.1mm) short and the Pilot
Release Stock Clamp will allow the pilot pin to pull the
material under the clamp pad into the proper position.
MECHANICAL PILOT RELEASE
The Mechanical Spring-Loaded Pilot Release Clamp
is installed in place of the standard Stock Clamp. Turn
the Hex Nut to compress the Spring for the desired
clamp and material pressure. Not available on LX.
PNEUMATIC PILOT RELEASE
The Pneumatic Pilot Release can be used for those
applications that require more sensitive clamping
pressure, or that the Clamp pad be completely free
of the material. With this system, the clamping
pressure may be adjusted by regulating the air
supply to the valve. The clamp pad is fitted with a
quick-response cylinder for positive stock grip and
release. Timing is controlled by an external 4-way
Solenoid valve or spool valve.
INTERNAL PILOT
RELEASE (IPR)
This internal valving system
provides up to 270 pounds
of clamping force with the
standard clamp and is
available on all FX, HX, and
LX models. The Internal Pilot
Release controls the release
of the Stock Clamp with a
timed air signal connected to
the 1/8" NPT port. This
feature gives you the option
of using pilot release, or not,without the downtime
necessary for changing clamps. One switch turns the
system on or off. The IPR requires an external 3-Way
Spool or Solenoid Valve.
