Norgren P64F-6GC-NFA Olympian Plus soft start dump valve - G3/4
Part Number: P64F-6GC-NFA
Quick Summary
Norgren P64F-6GC-NFA soft start dump valve improves start-up control for pneumatic machinery applications. Engineers often confront damaging pressure spikes and ramp-up delays that increase wear and downtime, and this valve is designed to deliver a smooth downstream pressure rise. It supports European Machinery Directive compliance and PUWER alignment, helping equipment meet regulatory requirements without redesign. The Olympian Plus platform combines high flow with reliable actuation, enabling efficient start-up sequences in production lines. This valve also supports compact installation and straightforward integration with existing manifolds, making it a prudent choice for industrial automation projects where uptime and safety matter. Its robust zinc alloy body and nitrile elastomer seals ensure longevity in harsh factory environments while delivering predictable response to control signals.

Soft-start capability with high forward flow reduces surge during start-up, extending tool life and cutting downtime in production lines. This translates to measurable efficiency gains and lower maintenance costs, particularly in clamping and transfer applications where controlled ramp-up is critical for process stability. The solenoid pilot with spring return enables reliable control from standard PLCs, minimizing electrical noise and simplifying integration with existing automation networks while ensuring safe reset after power loss. Compatibility with common fittings and the 3/2 valve configuration supports rapid retrofits and scalable line expansion, reducing project risk when upgrading older equipment. The G3/4 port size and Rc1/8 gauge port simplify plumbing and diagnostics, while the 57 dm3/sec flow (121 scfm) delivers robust actuation even under moderate system pressures. Durable zinc alloy body and nitrile elastomer seals withstand industrial environments and temperature range from -20 to 50 °C, delivering consistent performance. Accessories such as the Olympian Plus plug-in shut-off valve, wall brackets, and yoke assemblies streamline mounting, while documented data (CAD, datasheet, installation guide) supports compliant installation and traceability in regulated facilities.

FAQs
Yes. The valve uses a G3/4 port with Rc1/8 gauge ports, matching many standard manifolds and fittings. Its 3/2 valve arrangement simplifies integration with existing control logic, and it complements Olympian Plus modules. For retrofits, you can leverage compatible accessories such as the T64T-6GB-P1N plug-in shut-off valve and mounting options like 74504-50 Wall Bracket or Y64A-6GA-N1N/N2N yoke assemblies to ensure a secure, serviceable installation.
The P64F-6GC-NFA delivers a flow of 57 dm3/sec (121 scfm) and operates over a pressure range of 3 to 10 bar (43 to 145 psi). It is designed for -20 to 50 °C, ensuring predictable performance across typical factory environments. The 3/2 valve operation supports controlled venting and actuation, enabling smooth ramp-up without surges that could destabilize downstream tooling.
This valve excels in start-up sequencing for pneumatic machinery such as clamping stations, transfer lines, and handling systems where rapid, controlled pressure ramp is essential. The high forward flow capacity supports quick readiness of downstream actuators, while the solenoid pilot / spring return arrangement provides reliable PLC-driven control. It is particularly beneficial in lines subject to PUWER considerations and European machinery directive context.
The P64F-6GC-NFA is designed to aid compliance with European machinery regulations by enabling controlled start-up, which reduces risk during ramp-up. While the data emphasizes regulatory alignment with the Machinery Directive and PUWER, users should verify any specific CE labeling or certification requirements for their installation. The valve’s documented compatibility and installation guides help ensure compliant integration in regulated facilities.
Maintenance is simplified by standard components such as spare coils (QM/48/13J/21) and off-the-shelf accessories like MB004B silencers. The valve’s durable zinc alloy body and nitrile seals minimize wear in harsh environments, delivering lower maintenance costs and longer service intervals. ROI is driven by reduced startup shocks, higher line uptime, and smoother automation that lowers scrap and throughput losses over time.
