Norgren P64F-2GC-PFA Dump Valve - G1/4, 3-10 bar
Part Number: P64F-2GC-PFA
Quick Summary
The P64F-2GC-PFA dump valve provides controlled pressure release for pneumatic startup and soft-start sequences in automated equipment. Engineers often grapple with unstable startup pressures that cause wear, vibration, and unplanned downtime on production lines. It helps meet regulatory expectations by supporting CE-related compliance under the European Machinery Directive and PUWER, easing safety and reliability audits. This solution integrates with the Olympian Plus family to deliver predictable startup behavior, reduce energy waste, and extend component life, while offering straightforward installation and compatibility with standard mounting options. By combining robust materials with proven actuation options, it delivers business value through higher uptime and lower total cost of ownership.

Downstream pressure control at start-up → Reduces startup surges, protects downstream components, and extends service life in automated lines. Application: pneumatic startups in packaging, assembly, and handling systems. Benefit: faster line readiness with fewer unexpected stops. Long-flow capability with 57 dm3/sec (121 scfm) enables higher cycle rates; Application: high-throughput machinery; Benefit: higher productivity and reduced cycle times. Solenoid pilot / spring return actuation → Simplified control wiring and reliable reset, improving fault tolerance. Application: any control logic requiring a fail-safe return; Benefit: easier integration and lower maintenance. Durable build using zinc alloy body and nitrile elastomer seals → Greater resistance to shop air contaminants, oil aerosols, and temperature variation. Application: harsh factory floors; Benefit: reduced part failure and lower replacement costs. Mounting versatility with wall brackets and yoke assemblies → Easy retrofit and flexible installation in existing layouts. Application: retrofits in older lines or compact spaces; Benefit: faster deployment and reduced installation costs. Regulatory alignment via Machinery Directive readiness and PUWER considerations → Compliance confidence for customers and audits. Application: European and UK plants; Benefit: smoother regulatory approvals and fewer project delays.

FAQs
Install the P64F-2GC-PFA by mounting it on a standard DIN/Rail compatible bracket or the included wall bracket, then connect the G1/4 inlet and the downstream ports. Use the Rc1/8 gauge port for pilot signaling as needed, and wire the solenoid pilot with a 24 V supply in the normal direction. Confirm 3/2 operation and leak-free seals.
Key performance specs include G1/4 port, 3-10 bar operating pressure, 57 dm3/sec flow (121 scfm), and 3/2 valve operation with solenoid pilot and spring return. This enables controlled ramp-up and reduced downstream surge. The device uses a zinc alloy body with nitrile elastomer seals for durability in typical industrial environments.
Yes. The P64F-2GC-PFA is designed to integrate with the Olympian Plus family and compatible accessories such as T64T-2GB-P1N plug-in shut-off valve and Yoke assemblies (Y64A-2GA-N2N, N1N). Mounting can be via the 74504-50 wall bracket, or standard yoke configurations. The gauge port Rc1/8 supports pilot feedback, simplifying retrofit into existing lines.
Primary regulatory support includes compliance with the European Machinery Directive, aiding CE readiness, and PUWER considerations for work equipment regulation. The design emphasizes safe start-up, controlled pressure ramps, and reliable operation to meet industrial safety requirements. Always verify local standards and add any required certifications for your market. This helps avoid regulatory penalties and enhances customer confidence.
ROI is driven by reduced startup time, less equipment wear, and lower maintenance costs. The P64F-2GC-PFA enables faster line ramp-up, minimizes pressure surges that damage seals, and extends service intervals for upstream/downstream components. When integrated with existing Norgren modules, lifecycle costs drop and overall plant uptime improves. ROI is also influenced by energy savings from controlled start-up and reduced accidental shutdowns, contributing to a shorter payback period for automation projects.
