PARKER’S LM-PRO MINIATURE, WIDE CONTROL RANGE, LOW POWER PROPORTIONAL VALVE ALLOWS FLOW FOR ALL VENTILATOR PLATFORMS

“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 Watts, the LM-Pro valve enables very 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 have power usage of less than 2 Watts, giving the customer longer battery life or ability to use 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), give the customer the ultimate in low and high flow rate and precision control proportional valve performance.

The Parker LM-Pro is a true, one-size-fits-all, proportional valve. 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 a great example of the portfolio of products at the Precision Fluidics Division of Parker Hannifin that lead the market in miniature, low power, light weight, high performance fluidic products.
