Kofloc, Model 6800 Series, Pressure Regulating Valve

Kofloc Model 6800 Pressure Regulating Valve

The Kofloc Model 6800 Pressure Regulating Valve is a high-performance, diaphragm-type regulator designed to provide ultra-stable outlet pressure even when the inlet pressure fluctuates. Built primarily for high-purity gas systems and analytical instrumentation, the Model 6800 utilizes a Stainless Steel (SUS316) diaphragm to ensure minimal gas adsorption and maximum resistance to corrosion.

With its compact design and precise adjustment mechanism, it is the ideal solution for protecting sensitive downstream equipment such as flowmeters, analyzers, and sensors from pressure surges.

Description

The Kofloc Model 6800 is engineered for “Set and Forget” reliability. While standard regulators often suffer from “creep” or pressure drift, the 6800 series employs a highly sensitive diaphragm and a precision-ground valve seat to maintain a constant delivery pressure.

The internal construction is designed with a “dead-space free” philosophy, making it suitable for high-purity gas applications where contamination must be avoided. The use of a metallic diaphragm instead of rubber ensures that there is no outgassing, which is critical for gas chromatography and semiconductor manufacturing. Whether you are managing carrier gases or high-pressure cylinder delivery, the Model 6800 provides the smooth, incremental control required for professional gas handling.

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

  • SUS316 Metallic Diaphragm: Prevents gas permeation and outgassing for high-purity applications.
  • Excellent Stability: Maintains constant secondary (outlet) pressure despite variations in primary (inlet) pressure.
  • Fine Adjustment: Features a multi-turn adjustment knob for minute pressure tuning.
  • Compact & Lightweight: Small footprint allows for easy installation in gas panels and laboratory benches.
  • High Durability: All wetted parts are made of high-grade materials (Stainless Steel and Fluororesin).
  • Wide Pressure Range: Available in various configurations to handle low-pressure laboratory needs or higher industrial demands.

Applications

The Kofloc Model 6800 Pressure Regulating Valve is essential for:

  • Analytical Instruments: Providing a stable baseline for Gas Chromatographs (GC) and Mass Spectrometers.
  • Gas Panels: Acting as a secondary regulator in gas cabinets for semiconductor processing.
  • Carrier Gas Supply: Regulating high-purity Nitrogen, Argon, or Helium from cylinders.
  • Pilot Plants: Protecting sensitive flow sensors and reactors from pressure spikes.
  • Medical Equipment: Ensuring steady gas delivery in high-precision oxygen or anesthetic systems.
