Agilent is pleased to offer Series 26 Aluminum Block Valves in partnership with VAT. Series 26 are compact, reliable valves used in rough to high vacuum applications for semiconductor and instrument manufacturing, R&D, and industrial vacuum systems. These block valves will reliably achieve 3 million cycles before first service in most applications. These valves are available in right-angle and in-line versions, and can be manually operated and pneumatically-operated. The pneumatic valve is also available with a position indicator. The position indicator delivers an electrical output signal when the valve cycles, and is user-set in either the normally-open or normally-closed position.
