The VSO®- MI is miniature proportional valve specifically designed for medical device manufacturers. Based upon Parker Hannifin’s benchmark VSO® design, the VSO®- MI miniature proportional valve incorporates thermal compensation to provide precise flow control and stability over a wide operating temperature range. The VSO®- MI miniature proportional valve is oxygen service clean and has been evaluated by registered laboratories to guidelines established within the ISO 10993-1:2009 matrix and USP regulatory standards for bio-compatibility. Together with integrated filtration and manifold seals, low power consumption and its light weight design, the VSO®- MI helps reduce the time and cost of system integration and compliance. The VSO®- MI miniature proportional valve is cost effective solution ideally suited for manufacturers of portable and stationary medical devices.
