ALD7 ultrahigh-purity diaphragm valve

August 3, 2022

Swagelok, a leading provider of fluid system products, assemblies, and related services, has announced the release of the Swagelok ALD7 ultrahigh-purity (UHP) diaphragm valve—a product capable of delivering the consistency and long service life necessary for semiconductor fabricators to improve chip yields. Compared to Swagelok’s current top-of-the-line ALD6 valve, the ALD7 provides better flow consistency, flow capacity, and actuator speed. It also offers the performance at high temperatures necessary to allow chip fabricators to overcome limitations in current production processes and keep up with demand.

ALD7 valves can be integrated into either new tools or legacy equipment to provide improved flow capacity (up to 0.7 Cv) in the same 1.5-inch (38.1mm) footprint as existing valves, helping fabricators keep up with the strong global demand for chips that power advanced technology. ALD7 valves deliver precise dosing over tens of millions of ALD (atomic layer deposition) production cycles by actuating more quickly and consistently than even its ALD6 predecessor. The actuator’s open and close response time can be less than 5ms. The actuator is immersible to 150°C (302°F) and the valve body is rated to 200°C (
