Description

The VSO®- MI is a miniature proportional valve designed for medical equipment 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 range of media. Unlike competitive valves in its class, the VSO® - MI miniature proportional valve has been tested to U.S. Pharmacopoeia (USP) Class VI requirements making it easier to achieve system compliance for toxicity and sensitivity. With integrated filtration, captive O-rings, flush manifold mount capability, low power consumption and light weight, the VSO® - MI is an efficient miniature proportional valve ideally suited for manufacturers of portable and stationary medical equipment.
