Manual SS Y Inline Valves (KF Flanged; Viton Bonnet)

Reliable and Economical Components for HV and UHV Applications

These valves are designed for high-vacuum (HV) and ultra-high-vacuum (UHV) applications where cleanliness and corrosion resistance are crucial. They offer a cost-effective solution for general-purpose use in demanding environments.

High Conductance Design

In the open position, the edge-welded bellows and valve seat move completely out of the gas path, enabling high conductance and smoother gas flow through the valve.

Key Features:

  • Low Leak Rate: The leak rate across the valve seat is as low as 2×10⁻⁹ mbar L/s, ensuring excellent performance in vacuum-critical systems.
  • Pressure Range:
    • Maximum pressure: Atmospheric pressure
    • Minimum pressure: 1×10⁻⁹ Torr
  • Superior Sealing: Features fluorocarbon o-ring seat seals, bellows-sealed shafts, and bonnet seals. For higher temperature applications or better vacuum conditions, copper seals are available.
  • Actuation Options: Valves are available in both manual and pneumatic configurations, providing flexibility to suit different system requirements.
  • Easy Maintenance: Routine repairs can be carried out without removing the valve body from the system, reducing downtime and simplifying maintenance tasks.

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.

Yes, we offer customized sputtering targets, evaporation materials, and crucibles to meet specific customer requirements for size, material composition, and purity.

Yes, we can assist in selecting the most suitable material based on your application, whether it’s for optical coatings, semiconductor fabrication, or decorative finishes.

Yes, we offer both bulk and small quantities of sputtering targets, evaporation materials, and spherical powders to support research, prototyping, and development projects.
