The valve applies fluid pressure unbalanced trim structure, the pattern of spool is selectable for needle-type or V-shaped, the valve has the features of small volume, light weight and high performance, and is used for precision control of micro flow. Like in precision chemicals and scientific research institute, it is applied to make precision micro control on flow rate and pressure. The minimum diameter of spool reaches 1mm, and minimum controllable CV is attainable to 0.001.
