Back Pressure Regulating Valve for Free Extrusion

Our MicroAir IV series features high-speed response times of less than 0.1 second (typically 20 milliseconds) for 50% full-scale changes, while standard MicroAir I and II models respond in approximately 2 minutes from zero to full scale.

Yes, our multi-channel models (2, 3, or 4 channels) are specifically designed for multi-lumen tubing applications, with each channel independently controlling pressure for separate lumens with its own display and range configuration.

We offer multiple control options including 0-10 volt input for PLC integration, contact closure inputs from diameter gauges, and manual 30-turn precision adjustment knobs, with some models supporting all three operational modes.

Accuracy ranges from ±0.1% of full scale for pressures below 60 inches of water to ±0.3% for higher pressure ranges, with repeatability of ±0.2% for low ranges and ±0.3% for 3-5 psi units.

MicroAir systems require minimal maintenance and feature a proven 10-20+ year lifespan. No calibration is required, and damping fluid never contacts process air, ensuring stable long-term operation with unlimited phone support included.

Yes, our MicroAir IV series with high-speed switching capability (response time <0.1 second) is specifically designed for bump and taper tubing applications, offering precise programmable control for rapid diameter changes during extrusion.
