81000 Series Aluminum Gate Valves
The 81000 Series Aluminum Gate Valves are designed for high vacuum applications specifically when pressure ranges approximate 1 x 10-7 mbar and bakeout temperatures do not exceed 150°C. These valves are designed for system integrators, designers and OEM’s within the Semiconductor, Solar, LED/FPD, Coating and BioPharm industries due to their robust design and low cost. They feature precision machined high strength aluminum bodies from solid 6061-T6 billet, dual quad ring long life shaft seals and high performance PEEK components.
