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).
Features
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.Special grease is used for the section not in contact with liquid to ensure outstanding durability.
