VAT’s Series 265 HV Aluminum Inline Valve is an excellent valve for pumping and venting of high vacuum systems.


Series 26 valves are bellows sealed and designed for high vacuum applications in pumping systems, semiconductor technology, research systems, etc.


Pneumatic valves come standard with a position indicator and without a solenoid valve. Solenoid valves are available upon request.
