The Precision Fluidics Division of Parker Hannifin Corporation has announced the release of its newest miniature proportional valve VSO® LowPro for controlling the flow rate of inert gases in medical equipment. Just 16mm (0.63in) wide by 14mm (0.55in) tall, the new valve addresses a key requirement for small portable devices where installation space is at a premium without compromising on a performance. Typical applications for the new to world VSO® LowPro 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 without sacrificing power.
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.
