TYPE CH, CHB & CHT
TYPES
BOTH DIRECTIONS FEED:
| 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:
| These units provide control in forward direction only, with unrestricted movement when retracting. |
REARWARD DIRECTION FEED:
| 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: 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.
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
