Norgren P64F-4GD-NFA Dump Valve - 3/2, 57 dm3/s
Part Number: P64F-4GD-NFA
Quick Summary
P64F-4GD-NFA is a compact Olympian Plus soft-start dump valve designed to control downstream pressure during startup in pneumatic systems. Engineers often face inrush surges that destabilize machinery, accelerate wear, and trigger safety interlocks during line start. This design supports regulatory alignment, helping you meet the European Machineries Directive and PUWER, with a clear path to CE compliance and safer startup sequences. Coupled with a G1/2 port, solenoid pilot and spring return actuation, it provides reliable, energy-efficient startup control across automation cells and packaging lines.

FAQs
To install, ensure the valve is mounted with access for wiring to the solenoid pilot and quick-release for maintenance. Use the G1/2 port connections and Rc1/8 gauge port for instrumentation. Mounting options include the 74504-50 wall bracket and compatible Yoke assemblies (Y64A-4GA-N2N/N1N) for stable frame mounting. Consider the optional T64T-4GB-P1N shut-off plug-in valve for simple shut-off during service. Spare coils QM/48/13J/21 are available if your control system demands frequent cycling.
The valve operates as a 3/2 configuration with a G1/2 port, rated for 3 to 10 bar (43 to 145 psi) and a broad operating temperature of -20 to 50 °C (-4 to 149 °F). Its flow capacity is 57 dm3/sec (121 scfm), enabling effective control of startup pressure while maintaining downstream stability. It uses a solenoid pilot with spring return for reliable actuation.
Yes. The valve’s soft-start capability reduces pressure spikes during startup, protecting downstream actuators and reducing wear on cylinders and clamps. With a robust zinc alloy body and nitrile elastomer seals, it handles the daily cycling typical of packaging lines. Its compact 3/2 design and standard porting simplify integration into existing automation cells, improving line uptime and reducing maintenance costs.
The P64F-4GD-NFA is designed to assist compliance with the European Machineries Directive and PUWER requirements, supporting a pathway to CE marking for EU-manufactured equipment. This alignment helps installers demonstrate safety-conscious startup behavior and equipment protection, contributing to lower risk during commissioning and ongoing operation in regulated production environments.
Plan for routine inspection of seals and the solenoid coil, with available spare coils QM/48/13J/21 to minimize downtime. The valve’s nitrile elastomer seals and zinc alloy body offer durable performance, but periodic checks of air quality, moisture, and contamination are advised. For longer service life, pair with the optional shut-off valve and ensure correct mounting with supported brackets and yoke assemblies.
