Technical confirmation notes
- Open the needle slowly from the fully closed position to avoid sudden actuator motion. Do not force the adjustment or rotate the product forcibly.
- A small residual air leakage is permitted even in the closed position. Do not use this product as a zero-leakage shut-off or isolation valve.
- Confirm the required flow-control direction with your inquiry. The dimensional model tables do not resolve that choice.
- Keep the tube-size and thread conventions shown in the tables. Use each drawing to interpret the other dimension symbols.
- The shared controller reference includes an elbow-type structure drawing; it is not an ASA-specific material breakdown.
