Norgren P64F-3GD-PFA soft-start dump valve - CE compliant
Part Number: P64F-3GD-PFA
Quick Summary
Norgren P64F-3GD-PFA is a soft-start dump valve designed to control downstream pressure in pneumatic systems during startup. Engineers often contend with startup surges that cause tool wear, energy waste, and unpredictable line behavior. This device supports CE conformity to the Machinery Directive and PUWER compliance, helping you meet regulatory requirements with minimal rework. With a 3/2 valve configuration, G3/8 ports, and a solenoid pilot plus spring return, it delivers reliable, repeatable startup control. Integrated into Olympian Plus systems, it pairs with Norgren accessories for easy mounting, quick commissioning, and long service life. By reducing pressure spikes and enabling high forward flow, it improves cycle times, reduces downtime, and supports safer, more predictable automation.

FAQs
Plan for a G3/8 inlet/outlet connection and Rc1/8 gauge port monitoring. Use compatible mounting accessories such as Y64A yoke assemblies or the wall bracket 74504-50 to simplify alignment. Ensure power to the solenoid pilot is within the 3/2 valve footprint and verify electrical compatibility with existing control cabinets. Adequate space for maintenance and clear routing of supply lines is recommended for long service life.
By providing a controlled pressure ramp at startup, the valve minimizes pressure spikes that stress downstream actuators and bleed valves. The high forward flow capability (57 dm3/sec) enables rapid system ramp while maintaining soft-start behavior, reducing cycle times and energy waste. This translates to less wear on tools and tighter process control in high-demand automation lines.
Yes. The P64F-3GD-PFA is designed to support CE conformity to the European Machinery Directive and PUWER compliance, helping you meet regulatory requirements with minimal engineering changes. This makes it suitable for new machinery builds and retrofits where regulatory alignment and safety are priorities, while maintaining reliable pneumatic performance.
Confirm operating pressure (3–10 bar) and temperature range (-20 to 50 °C) to match your application. Check port size (G3/8) and gauge port (Rc1/8) for compatibility with existing piping and sensors. Verify valve operation (3/2) and flow rating (57 dm3/sec) to ensure startup performance meets cycle time targets, along with material compatibility for the environment.
Consider the Olympian Plus plug-in shut-off valve T64T-3GB-P1N for startup isolation, Yoke assemblies Y64A-3GA-N1N or Y64A-3GA-N2N for mounting flexibility, and a 74504-50 wall bracket for secure enclosure mounting. Silencers MB004B reduce downstream noise, and spare coils QM/48/13J/21 ensure continuous operation during coil service or replacement. Regular maintenance should inspect nitrile elastomer seals for wear and integrity.
