Miniature Proportional Valve


Fluid Power Parker Hannifin proportional valve

Parker Hannifin's VSO LowPro series includes four orifice sizes ranging from 0.030” to 0.080”, three voltage levels (5, 12 and 24 Volts).

Parker VSO® LowPro Miniature Proportional ValvesParker Hannifan’s new model of the miniature proportional valves VSO LowPro utilizes a smaller orifice 0.030 in (0.76 mm) within the same small VSO LowPro footprint (0.63 in/16 mm wide by 0.55 in/14 mm tall) that creates an unmatched combination of size and flow control between 0 and 30 SLPM. Typical applications for the new model of the VSO LowPro valves include pressure control, volumetric flow control and pulse dose control. The VSO LowPro series focuses on reliability of operation and is qualified for up to 100 million cycles with a Reliability Factor of 0.96 and a Confidence Interval of 99%. The VSO LowPro family also allows designers to reduce power or battery size due to an efficient typical power requirement of 1Watt. The series provides engineers a breadth of configurations including four orifice sizes ranging from 0.030” (0.76 mm) to 0.080” (2.03 mm), three voltage levels (5, 12 and 24 Volts) and manifold mount accessories to handle air, oxygen or any non-reactive, non-condensing gases, while complying with Reach, RoHS, CE, IP65 and ISO 15001 regulations.
