The Precision Fluidics Division of Parker Hannifin Corporation, the motion and control technologies company announced the release of their new Parker LM-Pro Linear Motor Proportional Valve targeted at the respiratory and anesthesia markets.
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 100PSI (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 the 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.
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, lightweight, high-performance fluidic products.
