Needle Valve, Fully Adjustable
350 bar [5000 psi] • 11 l/min [3 US gpm]
DESCRIPTION AND OPERATION
This needle valve is a variable orifice used to create a pressure drop
when flow passes from port 1 to 2 or port 2 to 1. Clockwise rotation of
the adjustment screw decreases the flow setting until it is completely
closed. The setting can be locked by tightening lock nut or knob on the
adjustment screw.
