Parker Hannifin Precision Fluidics Division, Hollis, NH, announces its newest miniature proportional valve VSO® LowPro for OEMs looking for innovation in portability, comfort, and manufacturability when controlling the flow rate of inert gases in medical equipment. At just 16mm (0.63") wide by 14mm (0.55") tall, typical applications for the valve include pressure control, volumetric flow control, and pulse dose control in devices such as portable oxygen concentrators, ventilators, and patient monitors.

The VSO LowPro is qualified for up to 25 million cycles and offers typical flow rates of up to 50 SLPM with a maximum of 1.5W power at room temperature, which allows designers to reduce power or battery size supply. With an orifice of up to 2.03mm and a weight of 12g, the VSO LowPro, can perform the function of valves three times its size.

It offers a low profile design to simplify mounting, and eliminates cartridge configurations that are complex, expensive, and require machining. Engineers can choose between three orifice sizes, three voltage levels, and manifold mount accessories to handle air, oxygen, or any non-reactive, non-condensing gases, while complying with Reach, RoHS, CE, and ISO 15001 regulations.
