Valves
Needle Valves
Our needle valves give fine, precise flow control and positive shut-off on instrument lines. A non-rotating, hardened stem tip closes against a metal seat, so the valve seals tightly turn after turn without wearing the seat. Machined from solid bar stock and rated up to 10,000 psi, they come with TEQLOK™ tube ends or NPT threads.
