Technical Description
The Hydraulic Uni-directional Flow Control Valve (1/4" – 3/8" – 1/2") is designed for precise speed adjustment in hydraulic systems where oil flow must be restricted in one direction. Its one-way control mechanism ensures stable extension or retraction speed in cylinders, making it ideal for professional hydraulic applications.
Applications
Suitable for agricultural machinery, industrial equipment, mobile hydraulics, lifting systems, hydraulic presses, forestry machines, construction equipment, and any system requiring controlled single-direction speed regulation.
Operating Conditions
Designed for high-pressure environments up to 250–315 bar. Works with standard hydraulic oils (ISO VG 32–68). Ensures smooth operation even under load variation and continuous-duty conditions.
