Micro needle valve (flow rate control valve) FMNV1 series precision type
Caution
Product Description
A non-rotating needle valve that separates the rotating drive unit and enables the needle section to perform linear motion without rotation.
[Features]
· By making the needle section a non-rotating structure, smooth and precision flow rate control is possible (approximately 13 rotations).
· Fine adjustment is possible with linear, highly repeatable flow rate characteristics.
· Wide variety of needle ranges (flow rate ranges) and seal options available.
· You can select the needle that best suits your usage conditions from our extensive lineup of needles.
· You can select the shape from two types of main body shapes that matches your piping conditions.
· Wide range lineup of seal materials.
[Applications]
· Precision flow rate control for component gas analyzers, various analysis devices, gas detectors, and environmental measurement instruments.
· Precision flow rate control of combustion equipment such as general industrial furnaces, heating furnaces, vacuum furnaces, various burners, and other combustion devices.
· Micro flow rate control for various dispensers, two-component/liquid-gas mixing devices, mist generators, etc.

Behind the Scenes
We received many requests from customers in the analyzer industry, where reliability is essential, stating that standard needle valves lack accuracy.
They wanted to control flow rate more precisely and accurately at even lower flow rates, so we developed this product.
We offer a wide range of flow rate ranges not available from other companies, so by selecting the optimal needle number,
you can achieve optimal flow rate control according to your application.
