In-Line Needle Valves

In-Line Needle Valves

Flow rate is varied by a handwheel with a threaded stem and a tapered nose which passes through a fixed orifice.

Needle valve in-line

A locknut is provided on the threaded stem. The valve is installed in a hydraulic pressure line to provide infinitely variable flow in one direction, for instance limiting the maximum speed of a cylinder movement. When the required speed is set, the valve can be locked in position if required. If used in a test rig the valve can apply a variable and progressive back pressure to the test piece.
