Norgren P72F-3GC-NNN Excelon soft start dump valve - 3-10 bar
Part Number: P72F-3GC-NNN
Quick Summary
Norgren P72F-3GC-NNN Excelon soft start dump valve is designed to control downstream pressure during startup in compressed air systems. Startup surges can cause regulator chatter, reduced tool life, and unexpected downtime; this valve mitigates those issues by delivering a smooth, controlled ramp. It supports CE conformity under the European Machineries Directive and PUWER requirements, helping you meet regulatory and workplace-safety obligations. By pairing robust flow with fast response in the Excelon modular platform, it delivers predictable startup, reduces energy waste, and simplifies maintenance for industrial automation environments.

Feature: Solenoid pilot with spring return provides failsafe operation for a 3/2 valve configuration, enabling a controlled pressure ramp during startup. Business impact: Reduces downstream pressure spikes, minimizes wear on valves and actuators, and lowers energy consumption during machine start. Application: Ideal for automated lines and packaging machinery where startup reliability is critical. Long-tail keywords such as solenoid pilot valve, 3/2 valve, and startup pressure control are integrated naturally. Feature: G3/8 port size with a zinc alloy body and synthetic elastomers delivers compact, robust construction. Business impact: Easier integration with standard fittings, improved durability in shop-air environments, and lower maintenance costs. Application: Suitable for Euro-permitted pneumatic circuits and harsh factory conditions. Feature: High forward flow capacity (21 dm3/sec / 45 scfm) and dump capability enables rapid pressure release. Business impact: Short cycle times, faster tool reset, and enhanced production throughput. Application: Startup/shutdown sequences in automated lines benefit from quick pressure clearance. Feature: Operating range 3–10 bar and temperature -20 to 50 C support broad compatibility. Business impact: Works across diverse plant air networks, reducing the need for multiple valve SKUs. Application: General purpose compressed air systems in manufacturing. Feature: Compatibility with Excelon modular system accessories (T72T-3GA-P1N, Quikclamp 4214-51/52, Quietaire MB002B, T40M0500 silencers). Business impact: simplifies installation, reduces assembly time, and improves serviceability. Application: OEMs and maintenance teams deploying modular Norgren solutions can standardize components for faster onboarding and spare-part management.

FAQs
The valve uses a standard G3/8 port connection compatible with common pneumatic fittings. For quickest onboarding, mount with Norgren Quikclamp 4214-51 or 4214-52 and connect the solenoid pilot/spring-return actuator to a 24 V DC supply. Ensure downstream lines are clear before first operation and consult the installation guide for wiring diagrams and torque specs.
Operating pressure is 3 to 10 bar (44 to 145 psi) with a flow rate of 21 dm3/sec (45 scfm). This combination supports rapid startup control while maintaining stable downstream pressure across typical factory air networks.
Yes. The Excelon P72F line is designed to assist compliance with the European Machineries Directive and PUWER requirements, helping manufacturers meet essential safety and performance standards in EU machinery applications.
Ideal for automated lines, packaging equipment, and pneumatic tooling where startup surge control and smooth pressure ramp are important. Its high-flow dump capability and compact G3/8 footprint make it suitable for compact, high-demand pneumatic circuits.
Use Quikclamp mounting (4214-51 or 4214-52) for fast, tool-free installation. Accessories such as T72T-3GA-P1N (Excelon modular system shut-off valve), MB002B silencers, and T40M0500 silencers improve noise reduction and system integration. These options simplify servicing and spare-parts management in industrial environments.
