Norgren P64F-NNM-NNN Soft Start Dump Valve - 3-10 bar
Part Number: P64F-NNM-NNN
Quick Summary
Norgren P64F-NNM-NNN is a soft-start dump valve that regulates downstream pressure during machine startup. It prevents pressure surges that stress lines, reduces wear, and minimizes downtime in pneumatic systems. The unit is CE-marked and supports compliance with the European Machinery Directive and PUWER, helping you meet regulatory requirements without redesign. With solenoid pilot operation and spring return, it delivers a 3/2 valve action and high forward flow, supporting fast, controlled start-ups. This valve integrates smoothly with the Olympian Plus family, offers easy installation (without a yoke), and provides predictable, repeatable performance for demanding production lines in industrial automation environments today, and future-proof your line.

FAQs
Install without a yoke benefits compact layouts. Use the 74504-50 Wall Bracket or compatible Y64A yoke assemblies (N1N, N2N, N3N) to ensure reliable alignment. Place the valve in a clean, dry compressed-air line and position for easy access to the solenoid connection. Verify supply pressure is within 3–10 bar and that electrical wiring follows local codes.
At 6 bar, the P64F-NNM-NNN delivers 57 dm3/sec (121 scfm) flow in a 3/2 configuration with solenoid pilot and spring return. This enables controlled startup, reduces surge, and improves cycle times. For high-speed lines, minimize downstream pressure drop by proper piping layout and mounting to preserve performance.
Yes. The valve is CE-marked and designed to support compliance with the European Machinery Directive and PUWER. By delivering controlled startup pressure and safe actuation, it helps meet regulatory expectations during line commissioning, reducing risk and simplifying acceptance testing for machinery across packaging and general automation.
The P64F-NNM-NNN uses a zinc alloy body and nitrile elastomer seals, delivering durability in typical factory environments. Regular inspection of the solenoid coil, seals, and mounting hardware is recommended. With standard Olympian Plus components, spare parts are readily available, minimizing downtime and expediting field service.
Yes. The P64F-NNM-NNN is designed for compatibility with the Olympian Plus family and optional Y64A yoke assemblies, as well as mounting accessories like the 74504-50 Wall Bracket. This enables quick integration with existing piping and control panels, supports scalable multi-valve arrays, and simplifies spare-parts planning across automation projects.
