Norgren P64F-NNC-PFN Soft Start Dump Valve - IP65
Part Number: P64F-NNC-PFN
Quick Summary
P64F-NNC-PFN soft start dump valve streamlines pneumatic startups by providing a controlled pressure ramp for downstream circuits. Many machine lines suffer from pressure spikes, startup shocks, and wear on actuators, leading to downtime and maintenance costs. This solution supports compliance with the European Machinery Directive and PUWER, and it delivers IP65 protection when used with a sealed plug. The compact Olympian Plus design fits tight spaces and works with standard Y64A yoke assemblies for fast installation, delivering reliable operation across packaging, automation, and general plant environments. By reducing peak loads, it lowers energy consumption and extends component life, offering a clear business case for modernizing old plant air systems.

FAQs
The valve is designed with a port without a yoke and can be mounted using the 74504-50 wall bracket or compatible mounting options. For easy retrofits, consider the Y64A yoke assemblies (N2N, N3N, N1N) to reuse existing piping. Ensure proper wiring of the solenoid pilot and spring return to a PLC controlled output for reliable operation.
Operating pressure range is 3 to 10 bar (43 to 145 psi), with a downstream flow of 57 dm3/s (121 scfm). These specs support rapid venting of downstream actuators while maintaining controlled ramp during start-up, suitable for mid- to high-flow pneumatic circuits.
Yes. The design assists machine builders in meeting the European Machinery Directive and PUWER requirements. IP65 protection with a sealed plug further enhances safety and reliability on the factory floor, supporting CE considerations when properly installed in compliant enclosures.
Durability comes from a zinc alloy body and nitrile elastomer seals, plus IP65 protection against dust and moisture. The operating temperature range of -20 to 50 °C expands applicability across varying factory climates, while the compact form factor minimizes space requirements and simplifies integration.
Regular inspection of seals and the sealed plug is recommended. Use compatible yoke assemblies (Y64A series) and standard mounting hardware to simplify maintenance and retrofits. When replacements are needed, rely on serviceable components and follow a consistent preventive maintenance schedule to maximize uptime.
