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.
