FAQs
The P64F-NNL-NNN is designed for flexible mounting with optional Yoke assemblies (Y64A-4GA-N2N, N3N, N1N) and mounting accessories such as a wall bracket. It uses a without yoke port configuration, enabling straightforward retrofits or new builds. For best results, pair with compatible silencers and mounting hardware to minimize vibration and noise.
Key specs include a 3/2 valve operation, 3 to 10 bar operating pressure range (43 to 145 psi), flow capacity of 57 dm3/sec (121 scfm), and solenoid pilot with spring return actuation. The medium is compressed air, and the maximum operating temperature is -20 to 50 °C, making it suitable for a wide range of industrial environments.
Yes. The P64F-NNL-NNN is designed to assist compliance with the European Machinery Directive and PUWER regulations. This makes it well-suited for machines entering service in European markets, helping to reduce regulatory risk, ensure worker safety, and simplify certification during audits.
Best suited for automated production lines, packaging and assembly conveyors, and any equipment requiring controlled startup sequences. Its soft-start behavior minimizes surge pressures, while the 3/2 configuration supports straightforward integration into PLC-controlled controls. The rugged zinc alloy body supports long service life in tough environments.
Expect reduced startup wear and energy consumption due to controlled pressure ramping, leading to lower maintenance costs and less downtime. Compliance alignment with CE and PUWER can shorten regulatory cycles, while a compact footprint and flexible mounting help minimize installation time and spare-part inventory, delivering faster time-to-value.
