Very accurate, stable control of ultra-minute flows up to 1 ml/min possible
2.Wide variations of needle type
15 types of needles are available for your choice of the type that best suits your needs.
3.Needle of non-rotary structure
Because this valve is constructed so that the rotation of the regulating screw is transformed into linear motion of the needle, the valve has a longer life in addition to superior control performance.
4.Superior temperature characteristic (15-35°C)
The valve counts on an outstanding temperature characteristic (flow fluctuations remain within an insignificant range of 0.3%/°C to ambient temperature variations) thanks to the temperature compensation system incorporated in the valve's needle and orifice. This temperature compensation system is a utility model of KOFLOC registered at the United States Patent and Trademark Office. (Optional specification for needles #SS1 to #3B-BS)
This temperature compensation system is applicable to gases only, and not to liquids, because the viscosity of a liquid may fluctuate depending upon the temperature conditions.
