Norgren P64F-4GL-NFA Valve - CE compliant, 3/2
Part Number: P64F-4GL-NFA
Quick Summary
The Norgren P64F-4GL-NFA is a soft-start dump valve that enables controlled startup in compressed air systems. For machine builders, startup surge can cause belt slip, piston wear, or clamping misalignment, leading to downtime. It supports CE compliance under the European Machinery Directive and PUWER-aligned safety practices, helping validate regulatory requirements in production environments. The Olympian Plus platform delivers high-flow capacity and precise pressure control, with a robust zinc-alloy body and nitrile elastomer seals. With versatile mounting options and compatibility with accessory valves, it fits both new installations and retrofits, delivering reliable startup performance and reduced total cost of ownership. This combination translates to improved machine reliability and simpler compliance documentation.

Soft-start control paired with a solenoid pilot and spring return provides a controlled ramp of downstream pressure, reducing hydraulic and pneumatic shock during actuation. Business impact includes extended cylinder life, fewer sudden line responses, and lower maintenance costs in automated packaging or assembly lines. This is particularly effective for 3/2 valve operation in compact G1/2 port configurations, enabling smoother start sequences in tight machine footprints. The valve offers high forward flow capacity—up to 57 dm3/sec (121 scfm)—which translates to faster cycle times and improved throughput in high-speed production lines. In practice, engineers notice fewer startup faults and more predictable clamping or gripping behavior, reducing touchpoints and operator intervention. The design supports PUWER compliance and CE marking, reinforcing regulatory alignment while maintaining minimal downtime.

FAQs
The P64F-4GL-NFA supports versatile mounting with a Wall Bracket (74504-50) and Yoke assemblies (Y64A-4GA-N1N/N2N). It uses standard G1/2 port connections and Rc1/8 gauge port for monitoring. For retrofit projects, you can pair it with the Olympian Plus plug-in shut-off valve (T64T-4GB-P1N) to simplify integration and serviceability. This modular setup minimizes downtime during upgrades and keeps footprint consistent with existing valve manifolds.
Key specs include a 3/2 valve operation, G1/2 port size, and a 3-10 bar operating pressure range (43-145 psi). The valve delivers up to 57 dm3/sec (121 scfm) of flow, enabling rapid but controlled pressure ramp. The actuation is solenoid pilot with spring return, ensuring fail-safe behavior. Operating temperature is -20 to 50 °C, supporting common factory environments, while the body is zinc alloy with nitrile elastomer seals for durability.
Yes, the design supports CE compliance under the European Machinery Directive and aligns with PUWER safety practices, aiding regulatory documentation and risk assessment. While it does not list SIL or IP ratings, its robust construction, predictable response, and certified safety alignment make it a strong fit for automation lines that require reliable startup control and regulatory conformity.
The soft-start feature gradually increases downstream pressure during actuator startup, reducing valve and cylinder shock, minimizing wear, and stabilizing clamping or gripping actions. This translates to longer component life, fewer unexpected downtimes, and smoother cycle times. The solution is particularly advantageous for high-speed lines and equipment sensitive to pressure surges, such as packaging machinery and automated conveyors.
A range of accessories supports installation and maintenance, including MB004B silenters for noise reduction, 74504-50 Wall Bracket for fixed mounting, and Y64A-4GA-N1N/N2N yoke assemblies for modular mounting. Spare solenoid coils QM/48/13J/21 provide quick coil replacements, while T64T-4GB-P1N plug-in shut-off valves simplify integration with Olympian Plus circuits. These options help reduce downtime and extend service intervals.
