Ultrahigh-purity ALD3 and ALD6 valves are designed to provide semiconductor manufacturers with dependable, high-speed dosing of precursor gases used to build up microchips layer by layer in deposition chambers. These high-performance ultrahigh-purity valves feature:

  • Ultrahigh cycle life with high-speed actuation
  • Flow coefficients ranging from 0.27 to 0.62, with custom flow coefficients available
  • Full immersibility up to 392°F (200°C) with optional thermal actuators
  • Suitability for ultrahigh-purity applications with standard 316L VIM-VAR stainless steel valve bodies
  • Modular surface-mount, tube butt weld, and Swagelok VCR® end connections
  • Electronic or optical actuator position-sensing option

ALD3 and ALD6 diaphragms are composed of a cobalt-based superalloy material that provides strength and corrosion resistance; their valve bodies are composed of 316L VIM-VAR stainless steel, making them suitable for ultrahigh-purity applications; and the valve seats are composed of fully fluorinated high-purity PFA to enable a broad range of chemical compatibility and excellent resistance to swelling and contamination.

Ultrahigh-purity ALD3 and ALD6 valves can be set up for normally closed and normally open pneumatic actuation, and they are available in a variety of configurations, including two-port straight and elbow designs; two-, three-, and four-port multiport valves and multivalve manifolds; and two- and three-port modular surface mount valves in 1.125 in. (ALD3 series only) and 1.5 in. platforms. Available thermal actuators, position sensors, solenoids, and optional body holes to accommodate heater cartridges can all provide additional value to a user depending on their specific processes.
