HVA Aluminum Gate Valve - 81000 Series
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 302°F. 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 to reduce friction and lower particle levels. For maintenance purposes, the body is split above the flange for minimal clearance when removing the internal parts for servicing, while the lower portion can remain on the system.
