Feature: Medium and compatibility — The P64F-NNC-PFA uses compressed air and delivers a high-flow dump facility, enabling rapid, controlled relief of downstream pressure during startup. Business impact: Reduces cylinder stall and valve chatter, improving cycle times and extending actuator life. Application: Ideal for automated production lines, packaging equipment and other pneumatic systems that demand smooth startup. Feature: Operating range and reliability — It operates from -20 to 50 °C and 3 to 10 bar, ensuring dependable performance in typical factory environments and harsh locations. Business impact: Maintains consistent pressure control across temperature and supply variations, reducing unplanned downtime. Application: Suitable for intermittent and continuous-duty machines in manufacturing. Feature: Actuation and control simplicity — Solenoid pilot with spring return drives a 3/2 valve, delivering fast, predictable start-up and straightforward electrical integration. Business impact: Lowers energy consumption and simplifies control logic, improving overall line efficiency. Application: Integrates with standard PLCs and control cabinets. Feature: Durable construction and materials — Zinc alloy body with nitrile elastomer seals deliver corrosion resistance and long service life. Business impact: Reduces maintenance cycles and replacement costs in demanding environments. Application: Fits robust industrial plants with frequent cycling. Feature: Installation flexibility — Optional Yoke assemblies (Y64A-4GA-N2N/N1N/N3N), wall mounting (74504-50), and accessories like MB004B silencer and QM/48/13J/21 spare coils support retrofit and noise control. Business impact: Quick retrofits, quieter operation, and easier spares management. Application: Retrofit projects and new line builds needing flexible mounting and reduced noise.

FAQs
If you’re retrofitting or deploying in new equipment, you can mount the P64F-NNC-PFA without a yoke, using the optional wall bracket 74504-50 for secure placement. The unit also supports Yoke assemblies (Y64A-4GA-N2N/N1N/N3N) if a yoke mounting is preferred, helping simplify retrofits and integration with existing Norgren line components.
The valve operates with compressed air, at temperatures from -20 to 50 °C, and pressures from 3 to 10 bar. It uses solenoid pilot / spring return actuation and a 3/2 valve configuration, with a flow rate of 57 dm3/s (121 scfm). The body is zinc alloy and elastomer seals are nitrile rubber, suitable for rugged industrial use.
Yes. The design and documentation support compliance with the European Machinery Directive and PUWER guidelines, aiding CE marking and regulatory adherence in plant new-builds and modernization projects. This makes it a reliable choice for automation systems where regulatory alignment matters for certification and risk management.
You can expect a controlled startup with reduced pressure surges, minimizing wear on downstream actuators and valves. The high forward flow capacity supports rapid line starts, which can improve cycle times. The compact Olympian Plus design and durable materials reduce maintenance needs and downtime, delivering measurable uptime gains in packaging, pick-and-place, and pneumatic handling applications.
Consider Yoke assemblies Y64A-4GA-N2N/N1N/N3N for flexible mounting, and the 74504-50 Wall Bracket for non-yoke installations. For noise reduction and airflow control, add MB004B silencers, and keep spare coils QM/48/13J/21 on hand for easy electrical maintenance. These options simplify retrofits and ensure continued availability of critical spare parts.
