The Allenair Cyl-Check ® is a self-contained oil filled unit which can be used in any tool or work feeding application, eliminating chatter caused by variations in power thrust and irregular loads, providing smooth, uniform and precise feed control. The unit can be coupled with a Pneumatic Cylinder or other linear motion and provides the flexibility required in many applications, without the costly expense of a completely hydraulic system. The Allenair Cyl-Check is a high quality unit carefully designed, produced, assembled, and tested to provide long trouble-free service.

DESCRIPTIONS


PARALLEL MOUNTING: These are individual Cyl-Checks ® which can be mounted parallel with most 1-1/2, 2”, 2-1/2”, 3” or 4” bore Allenair Cylinders. This is achieved by means of a common front Nose Mount, a Rod Tie Bar and Mounts to secure the back end of each unit. For Mounting Kits available see Pages 49, 50 and 51.

It must be noted that in parallel mounting, because of the opposing forces, a side-load condition is created on the rods. It is imperative that the rod of the air cylinder be securely fastened and not allowed to deviate from a straight linear motion. The Cyl-Check ® can also be mounted independently to control other linear motions. Care should be taken to insure alignment in such cases, so that the rod of the Cyl-Check ® is not subject to side thrust.

TANDEM MOUNTING: The Tandem Cyl-Check ® Assembly is an in-line assembly of a Cyl-Check ® and a 2”, 2-1/2”, 3” or 4” bore Allenair Type “A” or “E” Double Acting Air Cylinder. The major advantage of these units is that the side-load condition between the rods is completely eliminated due to the direct in-line coupling of the Cyl-Check ® and Cylinder Rods.

CYL-CHECK®

TYPES

BOTH DIRECTIONS FEED:
TYPES CHB PARALLEL MOUNTING
CHTB PARALLEL MOUNTING
These units provide fully independent control in both forward and rearward directions.
(Note: CHB 2-1/2 CANNOT be used with Mounting Kits CHMK-1 or CHMK-2.)

FORWARD DIRECTION FEED:
TYPES CHF PARALLEL MOUNTING
CHTF PARALLEL MOUNTING
These units provide control in forward direction only, with unrestricted movement when retracting.

REARWARD DIRECTION FEED:
TYPES CHR PARALLEL MOUNTING
CHTR PARALLEL MOUNTING
These units provide control in rearward direction only, with unrestricted movement when extending.

All of the above types can be supplied with the side tubing and control valve mounted on either the left hand side (specify LH) or right hand side (specify RH) of the unit, looking from rod end, with the reservoir on top.

OPTIONS

THREADED ROD EXTENSION (RAPID TRAVERSE): This consists of an increased threaded rod length with stop nuts, which allows the cylinder rod and tie bar to travel unrestricted until the tie bar comes in contact with the stop nuts, where checking action will begin. The correct length of extra threaded rod extension must be identical or longer than the length of unrestricted travel required. Note, however, that the stroke of the Cyl-Check ® need be no longer than the maximum checking length required, but must include the correct threaded rod extension when ordered. Available on individual and parallel mounted types only. Standard lengths of extra threaded rod extensions are 5”, 10”, 15”, 20” or 30”. Select nearest standard extra rod extension and Cyl-Check ® stroke.

SKIP CHECK (RAPID TRAVERSE): The Skip Check allows by-pass of the control valve permitting rapid traverse and intermittent checking action in the direction of control.

OPERATION: The Skip Check unit is basically a 2-way Piloted Valve. With either the “Air Operated” or “Solenoid Operated” model, rapid traverse automatically occurs until pilot pressure is applied. On the “Air Operated” model, air is supplied through the use of a separate 3-way valve. On the “Solenoid Operated” model, a 3-way normally open valve is an integral part of the Skip Check unit, and must have a constant pilot pressure supplied to it. With pilot pressure supplied to the top of the solenoid housing, rapid traverse will occur when solenoid is energized. If pilot pressure is supplied to the solenoid adaptor base rapid traverse will occur when solenoid is de-energized. NOTE: Pilot pressure must equal the operating pressure of the air cylinder used. If any other linear force is used, pilot pressure (P.S.I.) must be at least equal to THRUST (LBS.)/20. Please see Page 54 for pilot pressure port locations and dimensions.

NOTE: STANDARD VOLTAGES are 12, 24, 120 & 240/60 and 6,12 & 24VDC

Stop Check: The Stop Check unit permits stopping the rod movement for any length of time and at any position throughout the controlled stroke. As many stops as desired may be made.

OPERATION: The Stop Check unit is basically a 2-way Piloted Valve. With either the “Air Operated” or “Solenoid Operated” model, no stopping action occurs until pilot pressure is applied. On the “Air Operated” model, air is supplied through the use of a separate 3-way Valve. On the “Solenoid Operated” model, a 3-way normally closed valve is an integral part of the Stop Check unit, and must have a constant pilot pressure supplied to it. With pilot pressure supplied to the solenoid adaptor base, stopping will occur when solenoid is energized. If pilot pressure is supplied by means of a piped exhaust adaptor to the top of solenoid housing, stopping will occur when solenoid is de-energized. NOTE: Pilot pressure must equal the operating pressure of the Air Cylinder used. If any other linear force is used, pilot pressure (P.S.I.) must be at least equal to THRUST (LBS.)/20. Accuracy of Stop Check strictly depends on the accuracy and repeatability of the valve or switch actuating it. Please see Page 54 for pilot pressure port locations and dimensions.

ORDERING PROCEDURE (PARALLEL MOUNTING)


1) AIR CYLINDER CHOICE
(a) When choosing an Allenair Cylinder, in order to be able to mount the Rod Tie Bar, an additional rod extension and threaded length is required.

By specifying CH after the Cylinder nomenclature the factory will automatically supply the Cylinder with the dimensions shown in the chart.

EXAMPLES: E-2x4-CH-OS-RG
EV-3x10-CH-SDS-AAS-120/60

(b) On certain packaged installations involving an Allenair Valve-in-Head ® Cylinder, it will be necessary to increase the stroke of the Cylinder in order for the Inlet Port, Speed Control Screws, and Solenoid Housings to clear the Cyl-Check. When such an increase is necessary it will be based on obtaining a minimum difference of 3” between the stroke of the Cylinder and the stroke of the Cyl-Check ® on all bore sizes from 1-1/2” through 3”, and 1-1/2” on 4” bore Cylinders. The difference, whenever required, will be taken care of automatically by the factory, unless specifically requested otherwise.
