Agilent is pleased to offer Series 54 All-Metal Ultra High Vacuum Valves in partnership with VAT. These valves are specially designed for use in ultra-high vacuum systems where bake-out temperatures up to 300º C preclude the use of elastomers and low melting temperature metals. The valves are manually operated with a standard Hex wrench, so no Torque Wrench is required. Thanks to the “hard-on-hard” metal seals, these valves can be operated thousands of times before requiring maintenance. Series 54 valves require very little maintenance with maximum reliability and vacuum sealing from atmospheric pressure to below 10-11 torr (mbar).
