Norgren P64F-NGA-NNN Valves & Flow Control - 3/2 Valve
Part Number: P64F-NGA-NNN
Quick Summary
Norgren P64F-NGA-NNN soft start dump valve delivers controlled downstream pressure during machine startup in automated lines. This helps address startup shocks that slow lines and shorten component life. Designed to support CE readiness through EU Machinery Directive compliance and PUWER readiness, it also reduces the risk of regulatory nonconformance. The compact, air-pilot / spring-return action integrates easily with existing piping, delivering reliable startup sequencing, high flow, and robust operation in demanding industrial environments.

FAQs
The P64F-NGA-NNN is designed for mounting with optional yoke assemblies (Y64A-4GA-N2N, N3N, N1N) and wall brackets (74504-50). If no yoke is used, select compatible mounting hardware and ensure correct orientation for the 3/2 valve and air pilot actuation. The installation kit options simplify retrofit into existing piping and fixture layouts while preserving proper seal integrity.
Key specs include operating pressure 3 to 10 bar (43 to 145 psi), operating temperature -20 to 80 °C (-4 to 176 °F), flow 57 dm3/sec (121 scfm), and valve operation of 3/2 with air-pilot / spring return actuation. The medium is compressed air, with a zinc alloy body and nitrile elastomer seals, enabling reliable performance in typical industrial environments.
Yes. Its soft-start, dump valve capability provides controlled pressure ramp during startup, protecting downstream actuators and reducing shock loads. The 3/2 configuration, high flow capacity, and reliable spring-return actuation support rapid yet safe sequencing in packaging lines, improving uptime and preserving equipment life in high-throughput applications.
The P64F-NGA-NNN is designed to facilitate compliant startup sequences that align with the EU Machinery Directive, aiding CE readiness. It also assists with PUWER compliance by enabling controlled machine startup and safer operation, reducing risk during equipment commissioning and routine maintenance in industrial settings.
Durable zinc alloy body and nitrile elastomer seals provide robust wear resistance, supporting extended service life in repetitive start-stop use. The valve’s compatibility with silencers and mounting accessories enables quieter operation and easier retrofits, delivering lower lifecycle costs through reduced maintenance, fewer unscheduled downtime events, and improved return on investment.
