Kofloc Precision Needle Valve w/Non-rotary Needle Model 2412 SERIES

The Kofloc 2412 SERIES Precision Needle Valve represents the pinnacle of manual flow control technology.

Description

The Kofloc 2412 SERIES Precision Needle Valve represents the pinnacle of manual flow control technology. Unlike conventional needle valves where the stem rotates as it moves against the seat, the 2412’s needle stem does not rotate. This linear-only movement prevents “fretting” or galling of the valve seat, which is the primary cause of flow drift and particle contamination in high-purity systems

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC's corporate motto is "A Scientific Approach for Fluids." In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.

Specifications

  • Applicable fluids
    gas N2, Air, He, Ar, O2, CO2
    liquid H2O
  • Max Flow rate
    gas 5mL/min to 100L/min (air at 20℃, 0,1MPa differential pressure) up to woring conditions, for details see the reference data
    liquid 5mL/min to 2L/min (H2o at 20℃, 0,1MPa differential pressure)

Features

  • Non-Rotary Needle Mechanism: Linear stem movement prevents valve seat wear and eliminates particle shed for high-purity applications.

  • Ultra-Stable Flow Control: Eliminates flow drift and ensures superior repeatability even after thousands of cycles.

  • Hysteresis-Free Adjustment: Smooth, precise control without the “jumpiness” found in standard rotary needle valves.

Applications

  • Analytical Instrumentation: Precise carrier gas control for gas chromatography (GC) and mass spectrometry.

  • Semiconductor Manufacturing: Regulating specialty gases in cleanroom environments where particle contamination must be zero.

  • Precision Gas Blending: Creating exact gas mixtures for laboratory research and calibration standards.
