The Precision Fluidics Division of Parker Hannifin announced the release of the new Parker LM-Pro linear motor proportional valve targeted at the respiratory and anesthesia markets.

“The Parker LM-Pro miniature proportional valve utilizes a patent-pending linear motor actuation technology to enable flow up to 540 slpm in a very compact and energy efficient package, while providing an unparalleled, controllable range to allow for use across multiple respiratory applications,” says Beth Young, division marketing manager at Parker Precision Fluidics.

A critical feature of the LM-Pro valve is the valve’s linear motor actuation technology that provides exceptional resolution over a longer stroke and lower power consumption than traditional solenoid or voice coil actuation designs. With a linear controllable flow range from 0.5 to 540 slpm, pressure capability up to 100 psi (6.9 bar) and typical power consumption of less than 2 W, the LM-Pro valve enables precise flow control throughout the full performance range of the valve.

The LM-Pro valve allows for simple, closed-loop feedback, giving the customer precise pressure or flow control. This ensures accurate and safe delivery of precise gases to patients, from neonates to adults. Typical applications will require less than 2 W of power, giving users longer battery life or the ability to take advantage of a smaller battery to save size and weight. Typical hysteresis of <10% (full scale), coupled with a fast response time of <20 msec (full cycle), provides excellent low and high flow rate and precision control proportional valve performance.

The Parker LM-Pro is a true, one-size-fits-all, proportional valve, according to the company. Its unrivalled performance capability combined with the simplicity of a face mounted/ported design make the LM-Pro valve an ideal solution for varied applications with dynamic flow control needs. “It is ideal for customers who are trying to increase performance while continuing to decrease the footprint of their products,” says Paul Nierman, division engineering manager at Parker Precision Fluidics.

As systems become smaller and more portable, power concerns and accurate flow control at both the high and low ends of the spectrum are vital. The Parker LM-Pro linear motor proportional valve is one example of the portfolio of products suited for miniature, low power, light weight, high performance fluidic products.
