Norgren P64F-4GB-NNN Valve & Flow Control - Olympian Plus
Part Number: P64F-4GB-NNN
Quick Summary
The Norgren P64F-4GB-NNN valve is a controlled dump valve for pneumatic startups in automation equipment. Many machines struggle with sudden pressure spikes at startup, causing downtime and wear on seals and actuators. The design supports CE marking under the European Machineries Directive and PUWER compliance, helping integrators meet regulatory requirements. With a high flow dump capacity and a compact zinc alloy body, it fits in tight spaces while delivering reliable start-up control. This makes it a practical choice for OEMs and maintenance teams aiming to reduce risk, improve safety, and shorten commissioning cycles.

Feature → Business Impact → Application: The P64F-4GB-NNN uses an air pilot / spring return actuation and a 3/2 valve operation with a G1/2 port and Rc1/8 gauge port. This delivers a deterministic start sequence and fail-safe behavior, reducing startup variability in automated lines. Application: suitable for packaging, automation cells, and conveyor systems where controlled pressure ramp is critical for downstream equipment protection. The high forward flow capacity of 57 dm3/sec (121 scfm) enables rapid pressure build-up and quicker line readiness, boosting overall line throughput and reducing cycle times. Application: feed-forward start of clamping, gripping, and transfer mechanisms with minimal dwell time. The rugged zinc alloy body and Nitrile elastomer seals provide reliable operation across typical shop air conditions, lowering maintenance costs and extending service intervals. Application: integration in harsh manufacturing environments with consistent performance. Materials and operating range (body and elastomers) support long-term reliability and compatibility with standard compressed air systems. Application: OEMs planning long-term spares strategy. The unit’s design also supports easy mounting via standard fittings and compatible accessories, reducing installation complexity and accelerating retrofits. Application: quick on-site commissioning and minimal downtime during upgrades. Compliance-oriented features align with European directives, enabling quicker certification cycles for new machinery and reductions in project risk. Application: fleet-wide upgrades and new line integrations.

FAQs
The P64F-4GB-NNN uses standard G1/2 port connections and Rc1/8 gauge ports, making it straightforward to drop into common manifolds and existing piping. Compatibility is enhanced by available accessories such as the 74504-50 wall bracket and Yoke assemblies (Y64A-4GA-N1N, Y64A-4GA-N2N), plus the Olympian Plus plug-in shut-off valve T64T-4GB-P1N for integrated control. For retrofit projects, verify space for actuation access and ensure mounting hardware aligns with your manifold pattern to maintain leak-free operation.
Expect a controlled pressure ramp with a 3/2 valve operation, enabling a gradual downstream pressure increase. The valve supports a 3–10 bar operating range and provides a high forward flow capacity of 57 dm3/sec (121 scfm), which reduces startup time and improves process throughput. This is especially beneficial for clamping, gripping, and transfer sequences where rapid, safe initiation of downstream actuators is required.
Yes. The design supports CE marking under the European Machineries Directive, helping machine builders meet essential safety and performance requirements. It also aligns with PUWER for safe equipment operation in the workplace. When used as part of an integrated control system, this valve contributes to a compliant startup sequence and safer machine commissioning with reduced regulatory risk.
The valve features a zinc alloy body with nitrile elastomer seals, chosen for durability in typical compressed air environments. Operating temperature ranges from -20 to 50 °C, and operating pressure spans 3 to 10 bar, making it suitable for standard industrial air systems. These specs support reliable performance in workshops and production floors, while providing a predictable service life in routine automation tasks.
A range of mounting and integration options supports quick installation: Wall Bracket 74504-50, Yoke assemblies Y64A-4GA-N1N and Y64A-4GA-N2N, and the T64T-4GB-P1N plug-in shut-off valve. Silencers like MB004B Quietaire can be added for noise reduction. Leveraging these accessories simplifies retrofit and OEM installations, helping maintain compact footprints and clean, serviceable manifolds.
