Parker Announces New Miniature, Low Power, Extreme Flow Range Proportional Control Valve

Hollis, NH - The Precision Fluidics Division of Parker Hannifin, the global leader in motion and control technologies, announces the release of their new line of PACE Hf high flow proportional valves targeted at the Respiratory and Anesthesia Markets.

The PACE Hf proportional valve utilizes the Parker Advanced Technology Actuator to enable flow up to 500 lpm in a very compact and energy efficient package, while providing an unparalleled controllable range to allow for use across multiple Respiratory applications." says Todd Milne, Marketing Manager at Precision Fluidics Division.

Some of the critical features of the PACE Hf valve are that the valve has a wide controllable range from 0.5 lpm up to 500 lpm with a 0-10 VDC analog input controllable to 0.001 VDC increments. This enables precise flow control throughout the full performance range of the valve. The PACE Hf valve has an integrated sensor port that allows for simple, closed loop feedback giving the customer precise pressure or flow control. Typical applications will have power usage less that 1 watt, giving the customer longer battery life or ability to use a smaller battery to save size and weight. Typical hysteresis of <4% (full scale) coupled with a fast response time of <20 msec(full cycle) give the customer the ultimate in high flow proportional valve performance.

"With its impressive package size, the PACE Hf is ideal for customers who are trying to increase performance while continuing to decrease the footprint of their products." says Todd Milne, Marketing Manager at Precision Fluidics Division.
As systems become smaller and more portable, power concerns are increased. The PACE Hf 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.
