Norgren P64F-4GD-NNN Dump Valve - CE Compliance
Part Number: P64F-4GD-NNN
Quick Summary
Norgren P64F-4GD-NNN dump valve enables controlled pressure relief in pneumatic systems for machine automation. Engineers often struggle with startup surges and downstream overpressure that can accelerate wear or trigger safety faults. The design supports CE conformity under the European Machinery Directive and helps PUWER-compliance for safer, compliant equipment. With high forward flow capacity and solenoid pilot operation, it delivers reliable start-up control, reducing downtime and maintenance costs. This combination reinforces suppression of peak loads while keeping installation straightforward for OEMs and maintenance teams alike.

The primary feature is a solenoid pilot with spring return that provides a precise soft-start and dump function, which directly lowers startup surge risk and protects downstream actuators. Business impact: reduced mechanical wear, fewer unplanned stops, and easier commissioning of automated lines. Application: initial pressurization of clamped workpieces in packaging and machine tending systems, where controlled ramp-up improves cycle consistency and uptime.Operating at 3 to 10 bar and delivering 57 dm3/sec (121 scfm) of flow, the P64F-4GD-NNN supports rapid venting when needed, lowering cycle times and enabling predictable pressure release. Business impact: improved throughput and energy efficiency, with measurable reductions in pneumatics-related bottlenecks. Application: high-speed pick-and-place, robotic grippers, and machining centers that require dependable dump capability.Porting includes G1/2 inlet and Rc1/8 gauge port, simplifying integration with standard piping and existing manifolds. Impact: faster installation, reduced adaptor costs, and straightforward retrofits. Application: retrofitting older lines or expanding automation with minimal downtime.Durable construction uses a zinc alloy body and nitrile elastomers, delivering robust performance in typical factory environments. Impact: longer service life, lower maintenance costs, and consistent performance under temperature fluctuations (-20 to 50 °C). Application: textiles, food-and-beverage, and general industrial automation where moisture and grime are present.As part of the Olympian Plus family, the 3/2 valve configuration offers reliable actuation with compact form factor. Silencer MB004B reduces noise for compliant, comfortable workspaces. Impact: improved operator safety and regulatory adherence in noise-sensitive environments. Application: assembly lines and clean-room-adjacent environments where quiet operation matters.Optional mounting and accessory options, such as the 74504-50 wall bracket and Y64A yoke assemblies, streamline installation and serviceability. The T64T-4GB-P1N plug-in shut-off valve enables rapid disconnection for fault isolation. Impact: faster maintenance, easier field troubleshooting, and scalable configurations for growing systems.

FAQs
The P64F-4GD-NNN uses standard G1/2 inlet and Rc1/8 gauge ports, enabling straightforward integration with common pneumatic manifolds and fittings. It supports Olympic Plus accessories like wall brackets (74504-50) and yoke assemblies (Y64A-4GA-N2N / N1N), reducing retrofit effort and service downtime during upgrades or expansion.
This valve operates as a 3/2 configuration with a pressure range of 3 to 10 bar and delivers 57 dm3/sec (121 scfm) of flow. This combination provides rapid venting and reliable startup control, minimizing downstream pressure spikes and enabling more predictable actuator cycling in automated lines.
Yes. The Olympian Plus P64F family is designed to assist compliance with the European Machineries Directive and PUWER requirements by enabling controlled startup sequences and safer downstream pressure management, helping manufacturers meet regulatory expectations during machine design, modification, and maintenance.
With a zinc alloy body and nitrile elastomers, the valve is built for durability in typical factory environments. Regular inspection of solenoid coils, seals, and port connections is advised; replace elastomeric parts as needed to maintain seal integrity. The availability of accessories like silencers and shut-off valves supports ongoing noise management and fault isolation.
Upgrading to the Olympian Plus P64F-4GD-NNN can reduce downtime through predictable startup behavior and faster cycle times, lowering energy use and wear on downstream components. The ease of retrofit with standard porting and mounting options shortens installation time, delivering faster time-to-value and improved machinery availability.
