Norgren P64F-NNC-NFN Dump Valve - Soft start, 3-10 bar
Part Number: P64F-NNC-NFN
Quick Summary
Norgren P64F-NNC-NFN is a dump valve that provides soft-start, controlled downstream pressure for reliable pneumatic startup. Many machines face downtime or non-compliance during startup due to sudden pressure spikes. It supports European Machineries Directive compliance and PUWER guidance, helping you align design and operation with regulatory expectations. In addition, the valve leverages robust materials and high-flow performance to deliver predictable startup behavior and longer service life, while enabling efficient maintenance and retrofit options for broader equipment fleets.

Spare Coils
Feature → Business Impact → Application: The P64F-NNC-NFN delivers a controlled pressure rise on startup via a 3/2 valve configuration with solenoid pilot and spring return, reducing surge-related wear and energy spikes. This translates to lower maintenance costs and smoother actuator sequencing on packaging lines, automated assembly, and generic pneumatic systems. Application: Use during machine start-up to protect downstream actuators and ensure compliant commissioning across production cells. Feature → Business Impact → Application: With a 57 dm3/sec (121 scfm) flow capacity, the valve supports high-throughput startup sequences, enabling faster cycle times and reduced downtime in high-demand environments. Application: Suitable for high-speed conveyors and automated handling where rapid but controlled pressure release is required. Feature → Business Impact → Application: Durable zinc alloy body and nitrile elastomer seals offer long service life in harsh plant settings, cutting replacement intervals and downtime. Application: Industrial environments where resilience and leak-tight performance are essential. Feature → Business Impact → Application: Inline compatibility with Yoke assemblies (Y64A-4GA-N2N/N1N/N3N) and mounting options (Wall Bracket 74504-50) simplifies retrofits and new installations. Application: Retrofit projects or new lines where space and modularity matter. Feature → Business Impact → Application: Accessory ecosystem including MB004B silencer and QM/48/13J/21 spare coils streamlines maintenance, reduces spares holding, and supports fast field service. Application: Plant-wide reliability and serviceability for OEMs and integrators. Feature → Business Impact → Application: Compliance-oriented design supports European Machineries Directive and PUWER alignment during commissioning, reducing the risk of non-conformant installations. Application: Safe, compliant machine starts in EU-focused manufacturing environments.

FAQs
The P64F-NNC-NFN ships without a yoke but supports compatible accessories for retrofit and new installs. Yoke assemblies are available as Y64A-4GA-N2N, N1N, and N3N, and a Wall Bracket 74504-50 provides convenient mounting. Silencers MB004B and spare solenoid coils QM/48/13J/21 are available to optimize noise, performance, and maintenance.
Key specs include operating pressure 3 to 10 bar, flow 57 dm3/sec (121 scfm), and a 3/2 valve operation with solenoid pilot and spring return. These allow a controlled downstream pressure rise, reduce actuator shock, and support faster but safer startup sequences in pneumatic systems.
Ideal for packaging lines, automated assembly, and conveyor systems where startup surge control improves cycle times and equipment longevity. The high-flow capability ensures rapid pressure delivery to downstream actuators, while the soft-start feature minimizes wear and energy spikes.
The design supports European Machineries Directive and PUWER alignment by enabling controlled startup sequences and predictable performance. This helps engineers document compliant commissioning and safer machine operation within EU facilities.
Maintenance can be streamlined with readily available spare coils QM/48/13J/21, silencers MB004B, and Yoke assemblies. In retrofit projects, the compatibility with Y64A yokes and the wall-mount option simplify field service, while the zinc alloy body and nitrile elastomer seals offer long service intervals.
