Norgren EX14001BK4EE1 Proportional pressure control valve - IP66
Part Number: EX14001BK4EE1
Quick Summary
Proportional pressure control valve provides precise air pressure regulation for pneumatic systems across industrial automation. When signals falter or power shifts, output pressure can drift, causing cycle delays and unpredictable actuator behavior. This model supports explosion-proof and intrinsically safe configurations with IP66 protection and a robust fail-safe that drops unit pressure to zero on signal failure. Field replaceable filtration adds ease of maintenance, reducing unscheduled downtime. For OEMs and maintenance teams, it delivers safer commissioning, faster installation, and predictable performance in harsh environments, while enabling efficient remote monitoring and compliance with industry standards through 1/4" NPT ports and a 4-20 mA control loop.

FAQs
This valve uses standard 1/4" NPT ports for easy integration with common pneumatic manifolds and lines. The 4-20 mA control signal is designed to interface with typical PLCs and SCADA systems, enabling straightforward wiring, robust noise immunity, and reliable remote monitoring. When retrofitting, ensure compatible power supply, grounding, and proper signal conditioning to maximize control loop stability.
Operating temperature ranges from -40 to 85 °C (-40 to 185 °F), and operating pressure spans 0.2 to 1 bar (3 to 15 psi). These specs support stable performance across cold rooms, heated workshops, and general process lines while maintaining proportional control accuracy for sensitive actuators.
Yes. The EX14001BK4EE1 is designed for explosion-proof and intrinsically safe operation, with IP66 protection to resist dust and water ingress. This makes it suitable for hazardous areas where strict safety standards apply, such as chemical processing, oil & gas, and other zones where reliable pneumatic control is required without compromising safety.
Ideal for precise force control of pneumatic actuators, clamps, and regulators in packaging, automation cells, and robotic grippers. The 4-20 mA control allows integration with centralized control systems for closed-loop pressure regulation, improving cycle time, repeatability, and process stability in high-demand production lines.
The valve features a field-replaceable filter, simplifying on-site maintenance and reducing downtime. Regular filter checks combined with proactive pressure calibration minimize leakages and drift, extending service intervals, lowering total cost of ownership, and delivering faster line down-time recovery in high-demand environments.
