Norgren P64F-4GC-PFA Dump Valve - G1/2, 3-10 bar
Part Number: P64F-4GC-PFA
Quick Summary
Norgren P64F-4GC-PFA is a soft-start dump valve for controlled pneumatic startup in automation and packaging lines. Uncontrolled startup can shock downstream equipment, causing wear, vibration, and regulatory compliance challenges. The device supports CE conformity under the European Machinery Directive and helps align with PUWER requirements for safe equipment practices. With G1/2 porting and a 3–10 bar operating window, it integrates seamlessly into Olympian Plus actuators, delivering reliable performance in high-demand lines. This valve also complements standard air-purge and machine-feed logic, delivering predictable response, reduced energy peaks, and longer service life for your factory assets.

Feature: Solenoid pilot / Spring return actuation provides fast, fail-safe switching. Benefit: Improves startup reliability and safety by ensuring a controlled ramp and a safe stop, reducing shock loads on downstream cylinders. Application: Ideal for automation lines that require predictable actuation and compliant risk mitigation. Feature: Valve operation is 3/2 with a G1/2 port and Rc1/8 gauge port. Benefit: Simplifies integration with common pneumatic islands and enables compact footprint in control panels. Application: Suitable for compact feed lines and cabinet installations where space is at a premium. Feature: High forward flow capacity at 57 dm3/sec (121 scfm). Benefit: Shorter cycle times and faster material handling without sacrificing control precision. Application: Large actuator and quick-fill-down systems in packaging and manufacturing cells. Feature: Operating range 3–10 bar (43–145 psi) and -20 to 50 °C capability. Benefit: Broad compatibility with existing plant air systems and resilience in varied environments. Application: Versatile for multiple line pressures and seasonal temperature swings. Feature: Materials - Zinc alloy body; Nitrile rubber elastomers. Benefit: Robust construction with durable seals resistant to standard shop air contaminants, reducing maintenance. Application: Long-term reliability in demanding production environments. Feature: Olympian Plus series compatibility and mounting options (e.g., 74504-50 Wall Bracket; Yoke assemblies Y64A-4GA-N2N/N1N). Benefit: Fast, repeatable installation and straightforward retrofit into existing Norgren platforms. Application: Retrofit projects and new lines that leverage Norgren’s modular ecosystem.

FAQs
Install the P64F-4GC-PFA by aligning the G1/2 port connections to your actuator manifold and securing the valve with the appropriate mounting hardware. Use the Rc1/8 gauge port for monitoring pressure if needed. For retrofit projects, leverage mounting accessories such as the 74504-50 wall bracket and Y64A-4GA-N2N/N1N yoke assemblies to ensure a rigid, vibration-resistant fit.
Key specs include a 3–10 bar operating range, G1/2 port size, 57 dm3/s (121 scfm) flow capacity, and 3/2 valve operation. Actuation is solenoid pilot with spring return, enabling rapid, fail-safe response. Temperature tolerance spans -20 to 50 °C, making it suitable for demanding production environments.
Yes. The design supports CE conformity under the European Machinery Directive and aligns with PUWER requirements to help demonstrate safe equipment practices in automated lines. It is especially beneficial in new installations and upgrades where compliance documentation and risk reduction are priorities.
Recommended accessories include the Olympian Plus 3/2 plug-in shut-off valve T64T-4GB-P1N for integrated control, as well as mounting options such as 74504-50 Wall Bracket and Y64A-4GA-N2N/N1N yoke assemblies for secure installation. Pairing with MB004B silencers can reduce sound levels in noisy environments.
Expect ROI from reduced startup shocks, extended actuator life, and lower maintenance due to controlled downstream pressure ramp. The high-flow capability supports faster cycles, improving throughput, while compliant startup reduces regulatory risk. Spare coils QM/48/13J/21 are available to minimize downtime during coil swaps.
