Norgren P64F-4GC-NFN Soft Start Dump Valve - 3-10 bar
Part Number: P64F-4GC-NFN
Quick Summary
Norgren P64F-4GC-NFN soft start dump valve delivers controlled pressure rise in pneumatic systems during startup. Designers and maintenance teams often struggle to meet European machinery directives while preventing startup surges that stress downstream equipment. This valve supports CE compliance with the Machinery Directive and PUWER alignment, helping you document conformity and reduce risk. Built on the Olympian Plus platform, it combines robust zinc alloy construction with standard G1/2 ports and a 3/2 valve configuration, delivering reliable startup control within typical factory environments while enabling straightforward manifold integration and maintenance.

FAQs
The P64F-4GC-NFN uses standard G1/2 ports and Rc1/8 gauge ports, simplifying retrofit onto manifolds or existing 3/2 or 3/2+solenoid configurations. Ensure compatible power supply for the solenoid pilot, confirm proximity to dampening zones to maximize surge control, and use the 74504-50 wall bracket or Y64A yoke assemblies for secure mounting. With these measures, installation minimizes vibration and leak paths while preserving startup performance gains.
This valve offers a controlled pressure ramp during startup by combining a solenoid pilot with a spring return mechanism, allowing deliberate downstream pressure buildup before full flow. The result is reduced shock loads on cylinders and downstream regulators, improving seal life and protecting delicate actuators in packaging, tooling, and automation lines.
Yes. The unit is designed to support CE compliance with the European Machinery Directive and PUWER considerations, aiding documentation and conformity in EU applications. While it is not a safety device by itself, its controlled startup capability helps mitigate risk in machine assemblies, supporting overall regulatory alignment.
The valve is solenoid pilot operated with a spring return, and spare coils are available under the QM/48/13J/21 designation. This supports quick coil replacement, reduced downtime, and compatibility with PLC-controlled sequences. When integrating, verify coil voltage and control logic compatibility with existing control cabinets.
Key accessories include the Olympian Plus plug-in shut-off valve T64T-4GB-P1N for modular control, quiet operation using MB004B silencers, and mounting options like 74504-50 Wall Bracket plus Y64A-4GA-N1N/N2N yokes. These items enable cleaner piping layouts, reduced noise, and faster field service while preserving startup control benefits.
