CommandValve Smart Electronic Butterfly Valve with Conflat CF 3.375" Flange and Viton Seals, Manual or USB Serial Operation

The Ideal Vacuum Products (IVP) series of CommandValves are smart electronic butterfly valves. They are a reliable, low-cost alternative to manual or pneumatic gate valves. CommandValves are operated either manually using onboard pushbutton controls, or by computer control via an integrated USB virtual serial port. These smart butterfly valves allow for open, closed, or partially open operation (users can select any angle between, fully open and completely closed). This makes CommandValves an excellent solution for vacuum system integration, remote valve placement, automation, and control, and precision throttling.

These IVP exclusive high flow butterfly valves feature a small footprint, the shortest possible gas path, high accuracy, fast closure time (~270ms), and typical leak rate of 1 x 10 std. cc/sec helium. CommandValves are rated for high vacuum applications to 3 x 10^-8 Torr, and for positive pressures to 15 psig. They have an operating temperature range of 0 to 50° C and a MTTR (Mean Time To Repair) of 30,000 cycles. CommandValves operate on 12 VDC (max current draw 0.5A) and each valve is supplied with a power supply and USB connection cable. The permeability of CommandValve O-ring stem seals does not allow them to be used for ultra-high vacuum.

This CommandValve has Conflat CF 3.375" bolt-through flanges, Viton seals, and a conductance of 85 liters/sec. Use silver plated bolts for connections and either Viton or copper conflat gaskets for the fittings.

CommandValve Applications
CommandValves can be used as roughing, backing, and high vacuum valves. Because they can be opened and closed incrementally in 0.1 degree increments, from 0 degrees (closed) to 90 degrees (fully open), these valves can be used for precision throttling of the exhaust or purge line where it is desirable to maintain a steady vacuum chamber pressure (i.e., for altitude simulation).


CommandValve Construction Materials and Available Flange Sizes
CommandValves are manufactured in the U.S.A. with valve bodies and butterflies made exclusively of 304L stainless steel. Replaceable O-ring seals are made of Viton. They are available in ISO KF sizes from KF-16 to KF 50, and in Conflat flanged sizes from CF 1.33 in. to CF 3.375 in.
