Kofloc Bellows Needle Valve Model 2450 SERIES

The Kofloc 2450 SERIES is designed specifically for environments where even the smallest amount of atmospheric contamination or gas leakage is unacceptable.

Description

The Kofloc 2450 SERIES is designed specifically for environments where even the smallest amount of atmospheric contamination or gas leakage is unacceptable. In traditional valves, the sliding motion of the stem against a seal can eventually lead to wear, creating potential leak paths or shedding particles into the flow stream. The 2450 Series solves this by using a high-durability stainless steel bellows that completely isolates the valve’s moving parts from the fluid path.

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.

Features

  • Bellows Seal Technology: Provides a perfect hermetic seal, eliminating stem leakage and preventing external air from entering the system.

  • Particle-Free Design: No sliding seals in contact with the fluid, making it ideal for ultra-high purity (UHP) gas delivery.

  • SUS316L Stainless Steel Body: High-grade materials ensure compatibility with corrosive gases and aggressive chemical reagents.

Applications

  • High-Vacuum Systems: Serving as a reliable gas ballast or leak-tight isolation valve for vacuum chambers.

  • Specialty Gas Distribution: Regulating toxic, corrosive, or flammable gases where external leakage must be prevented.

  • Analytical Instrumentation: High-sensitivity mass spectrometry and gas chromatography requiring zero atmospheric contamination.

  • Nuclear & Energy Research: Handling isotopes or sensitive gases in sealed experimental loops.
