Kofloc Variable Secondary Pressure Flow Controller Model 2203 SERIES

The Kofloc 2203 SERIES is the definitive solution for “Variable Secondary Pressure” challenges.

Description

The Kofloc 2203 SERIES is the definitive solution for “Variable Secondary Pressure” challenges. In many industrial and laboratory setups, the outlet of a gas line is connected to a system where the pressure is not constant such as a burner, a bubbling tank with changing liquid levels, or a chemical reactor. In these scenarios, a standard needle valve would require constant manual readjustment to keep the flow stable. The 2203 Series automates this process.

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
  • Max Flow rate
    gas 10mL/min to 20L/min (air at 20℃)

Features

  • Secondary Pressure Compensation: Automatically maintains a constant flow rate even when the outlet (downstream) pressure changes.

  • Integrated Precision Needle Valve: Features Kofloc’s high-performance valve for ultra-fine and stable manual flow settings.

  • High-Resolution Control: Designed for stable regulation of minute gas flows, starting from as low as 5 mL/min.

Applications

  • Gas Bubbling Systems: Maintaining constant airflow in fermentation tanks or chemical baths where liquid levels (and thus head pressure) vary.

  • Burner & Flame Control: Ensuring a steady fuel-to-air ratio even as burner back pressure fluctuates during operation.

  • Environmental Sampling: Stabilizing sample intake flows when pulling gas through filters that become increasingly clogged.
