General Description
Series N needle valves are ideal as speed controls on
hydraulic and pneumatic systems where a reverse flow
check is not needed. They provide excellent control
and a reliable shut-off in a very small envelope.
Operation
A two-step needle allows fine adjustment at low flow
by using the first three turns of the adjusting knob. The
next three turns open the valve to full flow, and also
provide standard throttling adjustments.
Features
The exclusive “Colorflow” color-band reference scale on
the valve stem is a great convenience and time-saver
in setting the valve originally and in returning it to any
previous setting.
A simple set screw locks the valve on any desired setting.
A tamperproof option (T) feature is also available to
prevent accidental or intentional adjustment of flow
setting.
