Electromagnetic Bellows Sealed SS Angle Valves (CF flanged)

Overview of Reliable General-Purpose Components for HV and UHV Applications

TFM provides dependable and cost-effective components tailored for high vacuum (HV) and ultra-high vacuum (UHV) applications where cleanliness and corrosion resistance are paramount.

Operational Efficiency

When in the open position, the edge-welded bellows and valve seat retract from the gas path, significantly enhancing conductance. These components can endure intermittent baking temperatures of up to 200°C (with a continuous rating of 150°C), effectively improving ultimate vacuum levels.

Key Features

  • Leak Testing: Each valve undergoes helium leak testing prior to shipment, utilizing a helium mass spectrometer with an impressive sensitivity of 2 x 10⁻¹⁰ std. cc/sec.
  • Seal Options: Poppet seals are constructed with fluorocarbon O-rings, while bonnet seals can be selected as either fluorocarbon or copper gaskets. Copper is recommended for higher temperature bakeouts and achieving superior ultimate vacuum.
  • Maintenance: Routine repairs can be conducted without the need to remove the valve body from the system, ensuring minimal downtime.

Electromagnetic Models

The electromagnetic models are designed for various high vacuum processes and include the following features:

  • Voltage Compatibility: Smaller valve models operate on a 24 VDC supply.
  • High Conductance: These valves are specifically engineered for applications requiring simple, compact electric valves that can perform down to 10⁻⁹ torr.
  • Versatile Applications: Ideal for pump systems, portable vacuum stands, and benchtop analytical systems.
  • Easy Installation: Installation is straightforward, requiring no pneumatic connections, gas bottles, or house air supply lines.
  • Coil Saver Design: A unique coil saver design minimizes the heat typically associated with conventional electric valves, making them suitable for temperature-sensitive gauge isolation applications.

FAQ

Sputtering targets are materials used in thin-film deposition processes to create coatings on substrates. They are used in industries like semiconductors, optics, photovoltaics, and electronics.

Evaporation materials are used in Physical Vapor Deposition (PVD) processes, where materials are heated and evaporated to form a thin film on a substrate. These are critical for applications in optics, wear protection, and decorative coatings.

Boat crucibles are used as containers for evaporation materials during PVD processes. They help to uniformly evaporate materials onto the substrate for thin film formation.

Sputtering uses energetic particles to eject material from a target, while evaporation involves heating a material until it vaporizes and deposits on a substrate. Both are common methods in Physical Vapor Deposition (PVD) for creating thin films.

Consider the material composition, purity, target size, and application-specific requirements such as the thickness and uniformity of the film.
