Precision Needle Valve Model 2412 Series with Non-Rotating Needle

Precision Needle Valve Model 2412 Series with Non-Rotating Needle

  • Ability to control minute minute traffic
    Very precise, stable ultra-micro flow control up to 1 ml/min
  • Wide variety of needle types
    Choose from 15 needle valve needles that best suit your needs.
  • Non-Rotating Needle Valve Needle
    Because the structure of the needle valve allows the rotating adjustment screw to be converted into a needle-type linear motion, the valve has a longer service life in addition to excellent control performance
  • Excellent temperature characteristics (15-35°C)
    The needle valve has excellent temperature characteristics (flow fluctuations are kept within a negligible 0.3%/°C relative to ambient temperature changes) due to the temperature compensation system in the needle and orifice of the needle valve. This temperature compensation system is a utility model for registered optional specifications for pins #SS1 to #3B-BS
    This temperature compensation system is only suitable for gases, not liquids, as the viscosity of liquids may fluctuate with temperature conditions.

* Due to operating conditions and instrumental errors, there may be differences between the values indicated (L/MIN)
in the table above and those that are actually used by the customer.
* The values shown in the table above are data for Model 2412L for illustrative purposes only. As compared with the 2412L, flows on the 2412T will
run less smooth when the flow rate increases. It is therefore recommended that the 2412L be used for flows of 5 L/MIN or more.
