New model expands miniature proportional pneumatic valve platform


Parker Hannifin’s Precision Fluidics Division has announced the release of its newest model for the miniature proportional valve VSO LowPro for OEMs looking for innovation in size, power, and manufacturability when controlling the flow rate of inert gases.

The new model utilises a smaller orifice 0.76mm (0.030”) within the same small VSO LowPro footprint (16mm/0.63” wide by 14mm/0.55” tall) that creates an unmatched combination of size and flow control between 0-30 SLPM. Typical applications for the new model of the VSO LowPro valve include pressure control, volumetric flow control and pulse dose control.

With the release of this new model Parker has expanded its pressure specifications for its new Model 3, and existing Model 4 and Model 5 valve up to 100psi (6.9bar) with flows up to 57 SLPM further increasing the range of capabilities within this platform. Additionally, 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 one Watt.

Parker’s continued expansion of its VSO LowPro series provides engineers with a breadth of configurations including four orifice sizes ranging from 00.76-2.03mm (0.030-0.080”) three voltage levels (5, 12 and 24V) 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.
