FAQs
The P64F-NNL-PFN is designed for straightforward integration in 3/2 circuits without a yoke, but for enhanced mounting and alignment you can pair it with Yoke assemblies (Y64A-4GA-N1N, N2N, or N3N). Use the wall bracket option (74504-50) for fixed installations, connect the solenoid pilot with a proper 24 VDC supply, and ensure the downstream port is correctly plumbed to the cylinder. This setup yields repeatable startup sequencing and minimizes misalignment-related leaks.
Verify medium as compressed air, operating pressure 3–10 bar (43–145 psi), operating temperature -20 to 50 °C (-4 to 149 °F), valve operation as 3/2, and actuation via solenoid pilot with spring return. Check flow capacity of 57 dm3/s (121 scfm) to ensure downstream volume can be filled without pressure spikes, and confirm the body material is zinc alloy with nitrile elastomer seals for durability in your environment.
Yes. The P64F-NNL-PFN is designed to support compliance with European machinery directives and PUWER requirements by providing controlled startup, safe pressure ramping, and robust, repeatable performance. When installed in accordance with Norgren recommendations and local regulations, it helps manufacturers meet safety and performance standards while maintaining production efficiency.
Keep spare solenoid coils (QM/48/13J/21) on hand to minimize downtime, and maintain the system with the MB004B silencers for noise reduction. Yoke assemblies (Y64A variants) and the 74504-50 wall bracket should be available for quick retrofits or reconfigurations. Periodic inspection of nitrile elastomer seals for wear, and verification of inlet/outlet connections, will sustain consistent startup performance.
The valve delivers a controlled startup ramp with high forward flow, reducing startup time and minimizing pressure surges that cause wear. This translates to lower maintenance costs, reduced downtime, and longer cylinder life in high-cycle lines. The compatibility with existing Olympian Plus components and easy retrofit options also shorten installation time, accelerating payback on automation projects.
