IVP Ideal Seal, Conflat CF 2.75 in. Butterfly Valve, 1.00 in. Thick, Manual Quarter-Turn, SS

These manual butterfly valves provide a low-cost alternative to bellows sealed gate valves. These valves manually turn from the fully-closed position to fully open with only a quarter turn of the knob. A patented design allows the sealing disk to center itself when closing, with even pressure around the copper knife edge O-ring. This design also helps to lower the amount of scuffing or rolling of the O-ring. Quarter-turn actuation, small footprint and the shortest possible gas path make manual butterfly valves the preferred choice for many applications.

These Ideal Vacuum Products vacuum butterfly valves are designed to have a low leak rate, typically on the order of 1x10^-9 std. cc/sec. Helium. These butterfly valves have a Conflat CF 2.750 in. vacuum flange for connection to the vacuum system. They are manually operated, made of Stainless Steel and are manufactured in the USA by Ideal Vacuum Products.
