Inline Unidirectional flow regulator (90°)
unidirectional in-line flow regulator with a 90° port orientation, allowing controlled flow from A to B while allowing free-flow in the return direction. The adjustable needle with locking screw makes it easy to set and hold your required flow rate in the field.
A robust zinc-plated body, high-pressure rating across all port sizes, and a choice of seal materials make this valve suitable for a wide range of hydraulic circuits in mobile plant, agricultural, and industrial applications.
