KOFLOC Model 2412 Precision Needle Valve

KOFLOC Model 2412 Precision Needle Valve

For engineers and researchers who are not satisfied with average flow control, the KOFLOC Model 2412 precision needle valve is the industry standard. This needle valve is specifically designed to control very small quantities of gas or liquid with unprecedented stability and precision. This makes the 2412 highly suitable for integration into analytical instruments, semiconductor production and critical R&D setups.

Unrivalled control precision

The design of the Model 2412 series stands out for a superior mechanical construction that ensures a linear flow characteristic. The key technical advantages for your system are:

• Stable flow control: thanks to the fine-pitch thread and optimised needle shape, the set flow remains constant, even with small adjustments. You can therefore count on reproducible results in your processes.
• Wide control range: available in various versions for flows from only 5 mL/min up to 100 L/min (air equivalent). That is why KOFLOC offers the right valve for virtually every application.
• Inert materials: made of stainless steel (SUS316) with high-grade seals as standard. This makes the valve resistant to a wide range of gases and liquids without contamination.
• Minimal dead space: the internal design minimises places where liquid or gas can stagnate, which is crucial for fast gas changes and purity.

Fields of application

The KOFLOC 2412 is the preferred choice of system architects for:

1. Gas chromatography: accurate control of carrier gases.

2. Mass flow calibration: as a reference valve in test setups.

3. Vacuum technology: controlled venting or dosing in vacuum chambers.

4. Chemical dosing: precision injection of liquid reagents.

Custom work and options

At Inacom we understand that integration requires more than just a good product. The 2412 series is also available as Model 2412M, fitted with a multidial (counter scale) for easy reading and quick reset to previous settings. This is essential for R&D environments where parameters are changed often.
