Norgren P64F-NND-NNN Dump Valve - Without Yoke
Part Number: P64F-NND-NNN
Quick Summary
Norgren P64F-NND-NNN dump valve is a soft-start device that delivers controlled downstream pressure in pneumatic systems, ideal for new machinery and retrofits. Startup surges can stress downstream actuators, trigger safety stops, and drive maintenance costs, but this valve ramps pressure smoothly to protect equipment and extend service life. The design supports CE-related compliance under the European Machinery Directive and PUWER, helping projects meet essential regulatory requirements. As part of the Olympian Plus family, it combines high flow with robust Zinc alloy construction and straightforward integration with standard compressed-air systems. This translates to faster commissioning, predictable performance, and lower total cost of ownership in industrial environments.

The P64F-NND-NNN provides a controlled increase of downstream pressure on startup, reducing shock loads and extending valve and cylinder life. This translates to measurable efficiency gains by reducing cycle times and downtime, making it ideal for packaging lines, automated assembly, and pick-and-place systems. Actuation is via solenoid pilot with a spring return, delivering reliable fail-safe operation and easier integration with common PLC controls in industrial environments. With a 3/2 valve operation and a 3-10 bar operating range, users gain precise start-up control across a wide range of applications, from clamping stations to conveyor feeders. The zinc alloy body and nitrile elastomer seals ensure durability in harsh factory environments while offering straightforward maintenance and long service intervals. The port size is without a yoke, enabling faster installation and simplified mounting alongside existing manifolds and mounting brackets. Compatibility with standard accessories, including Yoke assemblies (Y64A-4GA-N1N/N2N/N3N), a wall bracket (74504-50), and MB004B silencers, simplifies retrofit projects and reduces total installation time. High forward flow capacity (57 dm3/sec / 121 scfm) supports rapid pressurization and improved cycle times, benefiting high-throughput lines and demanding applications such as stamping, plastics, and robotics cells. Industry insight highlights that using Olympian Plus valves in compliant systems can reduce downtime by up to 20% and extend component life through controlled startup profiles, especially when upgrading legacy equipment.

FAQs
Installation without a yoke simplifies mounting directly to compatible manifolds or brackets. Verify port size compatibility, secure the valve to a flat surface or bracket using standard mounting hardware, and connect the control lines to the solenoid pilot. Ensure clean, dry compressed air and an appropriate filtration setup to maintain performance and longevity.
The valve operates between 3 and 10 bar (43 to 145 psi) and is designed for compressed air as the working medium. This range supports multiple startup scenarios, from light to high-load cycles, while maintaining stable downstream pressure during ramp-up.
Yes. The valve is designed to assist in meeting regulatory expectations under the European Machinery Directive and PUWER by enabling controlled startup sequences, reducing risk of equipment overload, and supporting safer, compliant machine commissioning during retrofits and new builds.
Yoke assemblies Y64A-4GA-N1N/N2N/N3N offer straightforward mounting options, while the wall bracket 74504-50 facilitates compact installations. For noise reduction in exhaust lines, the MB004B Quietaire silencer is compatible. These accessories simplify retrofit projects and improve overall installation efficiency.
Upgrading provides a controlled pressure ramp that reduces surge on startup, protecting downstream actuators and reducing wear. Expect faster commissioning, lower maintenance costs, and improved cycle consistency in high-throughput lines, along with easier compliance during machine upgrades.
