Quick Summary

Norgren P64F-NNL-PFA is a dump valve that provides soft-start control and controlled venting for pneumatic lines in automated machinery. Engineers often contend with startup surges and regulatory compliance, and this valve mitigates peak pressures to minimize wear and downtime. It aligns with CE marking under the European Machinery Directive and supports PUWER compliance by restricting downstream pressure during startup. Its compact, yoke-free design and robust zinc alloy body offer reliable performance in harsh environments while easing installation and serviceability. For manufacturers seeking measurable improvements, the P64F-NNL-PFA enables predictable venting, reduced cycle wear, and safer, compliant start-up across configurable line layouts.

Feature → Business Impact → Application: Medium is compressed air; this ensures a clean, dry supply and reduces system contamination risk while delivering consistent venting behavior across lines. In practice, users see improved reliability on packaging or automation conveyors as startup transients are damped. Feature → High operating pressure range; 3 to 10 bar enables compatibility with common industrial air systems and fast energy transfer during start-up, which translates to quicker line-up times on multi-press or pick-and-place cells. Feature → 3/2 valve configuration with solenoid pilot and spring return; enables compact footprint and straightforward retrofit into existing manifolds, delivering safer venting with minimal wiring footprint and fast fault recovery. Feature → Flow capacity of 57 dm3/s (121 scfm); supports high forward flow during start-up while maintaining downstream protection, reducing operational bottlenecks in high-demand cycles in automated labs and machine cells. Feature → Zinc alloy body with nitrile elastomer seals; offers robust durability against shop air contaminants and thermal cycling, lowering maintenance costs on high-use lines. Feature → Yoke-free port design (without yoke); simplifies installation in tight spaces and enables flexible mounting on compact manifolds, minimizing enclosure footprint and assembly time. Feature → Compatibility with Y64A yoke assemblies and 74504-50 wall bracket; ensures easy retrofit and secure mounting in existing lines, reducing integration risk and downtime. Feature → Accessories such as MB004B silencer and QM/48/13J/21 spare coils; support extended service life, reduced acoustics, and readily available replacement parts for quick maintenance.

FAQs

The P64F-NNL-PFA is designed for yoke-free porting to simplify mounting in tight spaces. It fits standard 3/2 configurations and can be added to existing PLC or valve manifolds using compatible mounting hardware such as the 74504-50 Wall Bracket and Y64A yoke assemblies. Ensure correct pilot coil connections (QM/48/13J/21 spare coils) and verify supply pressure within 3–10 bar for optimal venting performance.
Operating pressure range is 3–10 bar (43–145 psi), with a flow capacity of 57 dm3/s (121 scfm). Operating temperature spans -20 to 50 °C (-4 to 149 °F). The medium is compressed air, and the valve is configured as a 3/2 with solenoid pilot and spring return. These specs enable reliable startup venting while preserving downstream pressure integrity in typical industrial air systems.
Yes. The P64F-NNL-PFA is designed to assist in meeting the European Machinery Directive requirements for safe startup and venting. It also supports PUWER compliance by providing controlled pressure ramp during startup to reduce equipment risk and operator exposure. When integrated with proper guarding and safety controls, it helps maintain compliant, reliable machine operation in production environments.
Recommended accessories include Y64A-4GA-N2N, Y64A-4GA-N3N, and Y64A-4GA-N1N yoke assemblies for secure port connections. Mounting options such as 74504-50 Wall Bracket simplify surface mounting. For noise reduction, MB004B Quietaire heavy-duty silencers can be used. Spare coils QM/48/13J/21 are available for quick coil replacements, minimizing downtime during maintenance.
The zinc alloy body and nitrile elastomer seals provide durability against shop conditions, reducing routine maintenance. The compact, yoke-free design minimizes installation time and enclosure footprint, lowering upfront costs. High forward flow and controlled venting reduce startup wear and downstream shocks, contributing to longer equipment life and improved production uptime, yielding a favorable return on investment over the lifecycle.
