Needle Valves – NG Series Globe Body, NA Series Angle Body
The Chemline N Series Needle Valves are designed for fine throttling of corrosive and ultrapure fluids at low flow rates. Because the seal material is PTFE, these valves are suitable for aggressive chemicals where similar valves with elastomer seals will not stand up.

Features & Benefits
- Precise Control with Fine Adjustment
Precision machined seat and matching ground needle tip along with a 24 pitch fine thread stem (five turns from closed to full-open) provides for excellent flow control. Better control of reagents can mean significant cost savings. - High Chemical Resistance
All parts are plastic or PTFE. No elastomers or metal parts are used. - Lubrication Free
No silicone or other lubricants used. - Easy Maintenance
Seal wear is compensated for by hand tightening the cap (gland). Valve can be serviced in-line. Simply unscrew bonnet to remove complete topworks for inspection or disassembly. - Heavy Duty Construction
Thick stems.
