Precision Needle Valve
The twin-screw structure enables linear low characteristics and precise low adjustment, allowing for accurate low control.The diaphragm isolates sliding components from the luid medium, minimizing particle generation. All wetted parts are constructed with modified luoropolymer resin.

Notes
1. Before operation, ensure complete evacuation of air and liquid from both the valve and pipeline.
2. Product disassembly is strictly prohibited. Any dismantling may compromise original performance specifications. Voiding all quality warranties for tampered units.
3. Purge all residual chemical liquids from valves and pipelines using purified water or air. Ensure complete removal of contaminants before proceeding with subsequent operations.
4. To ensure optimal product performance, regularly inspect valves and accessories.
