Application
This 16C collet block is a stationary unit with a double-acting cylinder. It is effective on machine and assembly operations
that require reliable clamping and unclamping. Use the collet block as a single unit or mount multiple closers on rotary
tables, pallets, fixtures or tombstones for increased productivity.
Installation
1. Mount the collet block to a rigid flat surface.
2. Plumb your first supply line using 5000 psi (344 bar) rated steel tubing to the CLAMP 1/4 NPTF port of the
collet block and the normally OPEN 1/4 NPTF port of your control valve.
3. Plumb your second supply line using 5000 psi (344 bar) rated steel tubing to the UNCLAMP 1/4 NPTF port of
the collet block and the normally CLOSED 1/4 NPTF port of your control valve.
4. Plumb your control supply to the 1/4 NPTF pressure port of the valve.
5. This configuration maintains a closed collet until the valve is actuated.
Operation
1. Remove the supply from the valve.
2. Loosen the collet locking screw.
3. Insert the collet in the top of the collet block.
