Norgren P74F-4GC-PFN Excelon Dump Valve - IP65
Part Number: P74F-4GC-PFN
Quick Summary
The Norgren P74F-4GC-PFN Excelon dump valve provides a soft-start and controlled pressure dump for pneumatic startups. In many lines, sudden pressure surges cause shocks and wear, leading to downtime and maintenance costs. This design supports CE-compliant machinery design and PUWER integration, while IP65 sealing protects against dust and water in harsh environments. With robust aluminium construction and a compact footprint, it delivers reliability while simplifying compliance and maintenance for industrial automation projects. Featuring a 3/2 valve operation, G1/2 port, and compatibility with standard manifolds, it delivers precise, repeatable performance across packaging, automation and tooling applications. This makes it an effective choice for machine builders seeking regulatory alignment and reliable ongoing operation.

Soft-start and controlled pressure dump reduce startup shocks and downstream surge. This translates to longer actuator life, quieter cycles, and fewer unexpected stops that disrupt production. Applications include packaging lines and automated assembly where sudden pressure can cause tool damage or misfeeds. Solenoid pilot with spring return provides fast, reliable actuation and a fail-safe reset. In practice this means PLC-controlled sequencing remains predictable even during power fluctuations, avoiding end-of-cycle stops and unsafe states. High flow capacity of 57 dm3/sec (121 scfm) supports rapid line ramp while maintaining protective downstream pressure. This sustains throughput, reduces cycle times, and is ideal for high-volume lines in automotive, packaging, and process automation. G1/2 port and aluminium body simplify integration with standard fittings and stock components, enabling straightforward retrofits and reduced project lead times. IP65 sealing with sealed plug protects electronics in dusty or washdown environments, lowering maintenance needs and extending service intervals. The P74F Excelon series also aligns with EU Machinery Directive and PUWER, easing regulatory reviews for OEMs and end-users. Compatibility with accessory ecosystems, including MB004B silencers and 4214 Quikclamp kits, helps optimize noise reduction and installation footprint in confined spaces. Overall, the design reduces life-cycle costs by improving reliability, enabling predictive maintenance, and accelerating time-to-value for automation projects.

FAQs
Begin by mounting the valve on a suitable panel or bracket using standard hardware. Connect the G1/2 ports to the supply and downstream actuator lines, then wire the 24V DC coil to your controller. Use an appropriate 22mm coil connector (M/P24121/1 compatible) and ensure the IP65 sealed plug is intact to maintain protection in harsh environments.
The valve supports the standard 22mm coil interface, with the M/P24121/1 Spare 22mm Electrical Coil Connector recommended for quick swaps. When selecting coils, verify coil voltage and protection class match your control system requirements and ensure compatibility with the solenoid pilot configuration for reliable operation.
Yes. The Excelon series is designed to assist machine builders in complying with the European Machinery Directive and PUWER regulations. Its IP65 sealing and robust build support safe, compliant operation in industrial environments, reducing the regulatory burden during machine integration and ongoing maintenance.
This valve operates from 3 to 10 bar and delivers a flow of 57 dm3/sec (121 scfm) with a G1/2 port. It is a 3/2 valve with solenoid pilot actuation and spring return, optimized for soft-start and controlled pressure dumps in compressed air systems, enabling predictable startup and protection for downstream components.
Recommended accessories include MB004B Quietaire silencers for R1/2 ports, Quikclamp fittings 4214-51 and 4214-52 for secure mounting, and the 22mm coil connector M/P24121/1 for coil replacement. These options help reduce noise, simplify mounting, and streamline wiring during installation in tight automation environments.
