Norgren P72F-3GL-NFA Excelon dump valve - 3-10 bar CNOMO
Part Number: P72F-3GL-NFA
Quick Summary
Norgren P72F-3GL-NFA Excelon soft start dump valve delivers controlled downstream pressure for pneumatic systems. Machine builders often contend with startup shocks, pressure spikes, and regulatory hurdles that slow line performance. This valve supports compliance with the European Machineries Directive and PUWER, easing safety assessments and reducing retrofit costs. Its modular Excelon family compatibility, corrosion-resistant zinc alloy body, and synthetic elastomer seals lower lifecycle costs while shortening downtime during changes or maintenance. With a G3/8 port, a 3-10 bar range, and solenoid pilot with spring return, it provides reliable, hands-off control for OEMs and maintenance teams seeking predictable startup sequences.

FAQs
When installing the P72F-3GL-NFA, select the G3/8 port orientation that aligns with your downstream actuators and ensure a clean, dry air supply within the 3-10 bar range. Mounting should follow standard DIN/ISO practices for compact 3/2 valves, with proper electrical connections to the solenoid pilot and a secure, vibration-resistant fit to prevent leakage or misalignment during rapid cycling.
The device employs a soft-start mechanism that ramps downstream pressure gradually, minimizing shock loads and peak currents at startup. This leads to smoother actuator movement, reduced wear on valves and hoses, and the ability to sustain higher line speeds without compromising control accuracy, making it well-suited for high-cycle packaging, clamping, and automation sequences.
Yes. The P72F-3GL-NFA integrates with the Excelon 72 modular ecosystem and is compatible with accessories like T72T-3GA-P1N modular shut-off valves, Quikclamp variants, Porting Blocks (e.g., 4216-52), and Excelon Plus adaptors. This enables rapid installations, straightforward retrofits, and scalable hydraulics/pneumatics configurations across new and existing lines.
The valve assists designers in complying with the European Machineries Directive and PUWER, supporting safety and regulatory readiness for EU machinery and equipment. While not a certification itself, its electrical actuation, predictable startup behavior, and modular design help meet industrial safety and performance criteria in automation projects.
Key specs include a G3/8 port size, 3/2 valve operation, 21 dm3/sec (45 scfm) flow, and an operating pressure of 3-10 bar. The solenoid pilot with spring return provides reliable actuation, while the temperature range of -20 to 50 °C supports diverse environments. Material construction uses a zinc alloy body and synthetic elastomer seals for durability.
