Stainless steel KF vacuum fittings, specifically made from SS304, are widely used in high-vacuum and ultra-high-vacuum systems due to their durability, corrosion resistance, and ease of use. Here’s an in-depth overview of a typical SS304 stainless steel KF vacuum fitting clamp set:

Features and Benefits:

1. Material:

   • SS304 Stainless Steel: Known for its excellent corrosion resistance and mechanical properties, making it ideal for vacuum applications where purity and cleanliness are crucial.

2. Design:

   • KF (Klein Flange) Standard: The KF fitting standard, also known as NW or ISO-KF, is a modular system for vacuum components and fittings that allows for easy assembly and disassembly.
   • Clamp Set: Consists of a clamp, centering ring with an O-ring, and sometimes additional hardware depending on the specific application.

3. Components:

   • Clamp: Typically a quick-release or wing nut style clamp that secures the flanges together.
   • Centering Ring: Ensures proper alignment of the mating flanges and includes an O-ring to maintain the vacuum seal.
   • O-Ring: Usually made from elastomer materials like Viton or NBR, providing a reliable vacuum seal.

4. Applications:

   • Vacuum Systems: Used in various vacuum systems, including research labs, semiconductor manufacturing, and industrial processes.
   • Scientific Instruments: Essential for mass spectrometers, electron microscopes, and other analytical instruments.
   • Pharmaceutical and Chemical Industries: Suitable for clean and hygienic environments.

Specifications:

Applications:

•Stainless steel sanitary Non Return valve is designed for use in stainless steel pipe installations to prevent reverse flow.

Operating Principles:

• When the lower pressure of valve stem over the upper pressure and spring force,check valve opens.

• When the upper pressure equal to the lower pressure,check valve closes.

• A higher reverse pressure acts on the valve stem and causes valve to closes.

Standard Design

•Check valve has two parts jointed together by clamp and sealed with the special gasket.This series has welded,clamped and threaded type,suits for kinds of pipeline connection.

Technical Data

•If the check valves are installed in a vertical pipe, it needs approximately equal pressure 6Kpa to open.Maximum pressure for conveying material is 1000Kpa,Using temperature scope for -10℃~+135℃.
