These
high conductance, stainless steel SS 304 fabricated
valves are designed for reliability and for use as
in-line chamber isolation valves and load lock
applications. These Gate valves are fitted with Neoprene
"O" rings as standard and optionally viton o
"O" rings are offered. Viton sealed valves can
be baked up to 150 deg.C under normal mode. These Gate valves
undergo stringent leak detection tests on a Helium Mass
Spectrometer for leak tightness up to 10-10
std cc/second. HINDHIVAC Gate Valves are offered in several models and can be operated
in both electro pneumatic as well as manual modes..
Gate
Valves are used immediately above the mouth of a
diffusion pump or above the water-cooled baffles. The
closure between the two sides is made by the movement of
a horizontal plate in its own plane, the seal being an
elastomeric. These valves are made in sizes of 1",
2", 4", 6", 8", 10", 20"
sizes as a standard product.
