Large Capacity Precision Needle Valve (for Stable Control)MODEL 2412D SERIES
This large capacity needle valve exhibits high performance in precision control of comparatively large flow. The needle valve is a larger version of our precision needle valve (Model 2412) that has time-tested reliability, and is suitable for stable control in a comparatively large flow range of 50–300 l/min (0.1 MPa).
1. The rotational motion of the flow control screw is changed into a linear motion to ensure smooth flow control without causing a screw gap.
2. The completely clean inside of the valve permits clean flow control.
3. A special grease is used for the section not in contact with the liquid to ensure outstanding durability.
