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.

✓ PTFE Seal - No Elastomers
✓ Lubrication Free No silicone or other lubricants used
✓ Heavy Duty Construction Thick Stems
