General Description<br />
Series “6N” needle valves are ideal as speed controls<br />
on hydraulic and pneumatic systems where a reverse<br />
flow check is not needed. They provide excellent<br />
control and a reliable shut-off in a very small<br />
envelope.<br />
Operation<br />
A two-step needle allows fine adjustment at low flow by<br />
using <strong>the</strong> first three turns of <strong>the</strong> adjusting knob. The<br />
next three turns open <strong>the</strong> valve to full flow, and also<br />
provide standard throttling adjustments.<br />
Features<br />
Meets ISO 6149 standards.<br />
Hard metric dimensions.<br />
Reliable leak-free per<strong>for</strong>mance — straight thread port<br />
with O-Ring sealing.<br />
Global interchangeablility.<br />
