Ultra-high purity diaphragm valve. Capable of approximately 100 million open/close cycles (under our test conditions) for atomic layer deposition (ALD) and high-speed switching (less than 5ms).
The Ultra Fast Series is designed for high-purity processes that require high-speed opening and closing at high temperatures, operating stably under precisely the same conditions, as exemplified by atomic layer deposition (ALD process) applications. It employs a unique flow control mechanism (patent pending US61/910,079) that allows for fine adjustments to maintain accurate flow rates during use.
