0-15 PSI Air Pressure Regulator with NPT Port

The available pressure ranges span from 0-3 inches of water up to 0-5 PSI, with some models also offering 0-10 inches of water, 0-15 inches of water, and 0-30 inches of water ranges. This variety of ultra-low pressure options allows manufacturers to select the most precise range for their specific tubing extrusion application.

All models feature ¼ inch NPT male fittings for standard industrial air connections, making them compatible with common industrial pneumatic systems and easy to integrate into existing extrusion lines.

Accuracy ranges from ±0.1% to ±0.3% of full scale depending on the pressure range and model selected. This high level of precision is achieved through hysteresis-free regulating action and viscostatic damping technology, ensuring stable and consistent tubing diameter control.

Response time varies by model type. Standard models have a response time of approximately 2 minutes, while high-speed models respond in less than 0.1 second — typically around 20 milliseconds. The high-speed response models are designed specifically for bump and taper tubing applications requiring rapid pressure switching.

Three control types are available: Manual Control (using a 30-turn precision knob for direct adjustment), Contact Closure Input (accepting Air Up and Air Down signals from O.D. gauges or other controllers), and 0-10 Volt Input (for connection to a PLC or other automated control device). This range of options allows the regulators to fit into both manual and fully automated extrusion environments.

Yes. In addition to single-channel models, On Line Controls offers Dual Channel, 3-Channel (MultiAir), and 4-Channel (MultiAir) configurations. The multi-channel models provide separate, independent air pressure control for each lumen, making them ideal for complex multi-lumen tubing geometries used in medical and other precision extrusion applications.

All units come with a three-year warranty covering parts and labor. Additionally, unlimited phone technical support is provided worldwide. The regulators are also designed to require no calibration and are built to maintain precision throughout a 10-20 year lifespan, reflecting the company's 40+ years of manufacturing excellence since 1980.
