The 1230 Valve can first be broken down into two main sections, the “Power Head”, and the “Wet Head.”

For simplicity sake, this manual will describe the procedures for a valve containing a luer-lock needle and

adapter.

To disassemble the 1230 into its main sections, refer to figure 6 and follow these steps.

1. Remove the Luer-Lock Adapter (24) and with the Luer-Lock Needle (25) from the bottom of the Valve.

2. Unscrew the Adjustment Knob (1) until it reaches the top of the scale, then press the Adjustment Knob

down until it bottoms out.

3. Remove the two lower 8-32 BHCS (9) from the front of the Valve and pull the Wet Head (B) section

from the Base (8), separate the Metering Rod from the Piston Rod, and remove the Wet Head.

4. Remove the two upper 8-32 BHCS from the front of the Valve and pull the Power Head (A) from the

Base.
