Norgren P64F-4GL-PFN Olympian Plus Dump Valve - 3-10 bar
Part Number: P64F-4GL-PFN
Quick Summary
Norgren P64F-4GL-PFN is a high-flow Olympian Plus dump valve for safe pneumatic start-ups in production lines. Engineers frequently battle startup pressure spikes that stress hoses and actuators, risking downtime and non-compliance with safety directives. It is engineered to support European Machineries Directive compliance and PUWER alignment, reducing the risk of regulatory gaps during installation and upgrade projects. With precise downstream pressure control and rapid flow, the valve helps deliver repeatable starts while preserving downstream equipment and energy efficiency. Coupled with its solenoid pilot/spring return actuation and compatibility with standard mounting and connection options, it integrates smoothly into existing assemblies and procurement strategies.

FAQs
The P64F-4GL-PFN supports standard G1/2 port connections with a Rc1/8 gauge port for sensing. Mounting accessories include 74504-50 Wall Bracket and Y64A-4GA-N2N/N1N yoke assemblies, plus silencer MB004B for noise reduction. It is designed to integrate with Olympian Plus plug-in components like T64T-4GB-P1N and spare coil options QM/48/13J/21, making retrofit and multi-valve installations straightforward.
The valve operates from 3 to 10 bar with a flow capacity of 57 dm3/sec (121 scfm). This enables a controlled and rapid ramp of downstream pressure during machine start-up, reducing shock loads on actuators and downstream circuits while preserving cycle times.
Ideal for automated production lines, packaging equipment, and tooling where start-up sequencing must be controlled and compliant with EU directives. Its high-flow capability supports quick start-ups, while the 3/2 configuration and solenoid pilot provide reliable actuation in demanding environments.
The Olympian Plus P64F-4GL-PFN is designed to assist machine designers in complying with the European Machineries Directive and PUWER by enabling controlled start-up pressure and safer operation. While it should be installed according to applicable standards, its robust construction and predictable performance help minimize regulatory risk during commissioning and upgrades.
Maintainers should monitor the solenoid coil (QM/48/13J/21) and ensure proper sealing with nitrile elastomers to prevent leaks. The modular design and available spare coils support quick field service, reducing downtime. The controlled ramp reduces wear and energy waste at start-up, yielding faster ROI through improved line availability and longer component life.
