Swagelok Launches New Ultrahigh-Purity Valve

Swagelok, a solutions provider of fluid system products and related services, recently released a new ultrahigh-purity (UHP) valve for high-flow applications. The ALD20 valve is the latest to come of Swagelok’s collaboration with semiconductor tool manufacturers and chip fabricators, allowing forward-thinking process designers the flexibility to experiment with low-vapor pressure chemistries.
The ALD20’s patent-pending design maximizes production process efficiency and deposition consistency by providing flow coefficients two and three times what can be achieved using today’s standard ALD valve technology. 

It can deliver a flow rate of up to 1.2 Cv in the same footprint (1.5 inches) as existing ALD valves, allowing some users to boost throughput without retooling existing equipment or making additional process changes. The other standard version ALD20 valve with a slightly larger footprint width (1.75 inches) provides an even greater flow rate of up to 1.7Cv. Custom set flow coefficients are also available.

Designed for peak process consistency, the ALD20 can be fully immersible in a gas box from 10°C (50°F) and up to 200°C (392°F), enhancing thermal stability and deposition uniformity. It also features a valve body comprised of 316L VIM-VAR stainless steel or Alloy 22 – offering enhanced corrosion resistance to withstand aggressive media.
