Manufacturer
Norgren
Part number
P64F-2GA-NNN

Quick Summary

Norgren P64F-2GA-NNN dump valve is a versatile soft-start valve designed for compressed air systems, enabling controlled pressure release during machine startup. This helps prevent damaging surge and reduces wear on downstream components. The design supports European Machinery Directive compliance and PUWER alignment, giving engineers a clear regulatory pathway. The valve's robust zinc alloy body and nitrile elastomers withstand industrial environments while providing reliable operation across the specified temperature and pressure range. By integrating the P64F-2GA-NNN, manufacturers can improve startup reliability, shorten setup times, and reduce risk of non-compliance in automated lines. For systems requiring high flow and precise control, this Olympian Plus device delivers both performance and value.

FAQs

Install the P64F-2GA-NNN by threading G1/4 pipe fittings to the inlet, outlet, and exhaust as per the schematic. Use the 3/2 valve configuration with air pilot and spring return, and connect the Rc1/8 gauge port for on-site pressure checks. Keep supply pressure between 3 and 10 bar, and verify alignment with PUWER and Machinery Directive requirements during commissioning.
The valve provides a maximum flow of 57 dm3/sec (121 scfm) with an operating pressure range of 3 to 10 bar. It employs a 3/2 valve configuration with air pilot and spring return, enabling precise startup control while accommodating typical factory air systems and downstream load requirements.
Yes. With its high forward flow capacity (57 dm3/sec) and the ability to dump excess downstream pressure on start-up, the P64F-2GA-NNN supports rapid cycle times and reduced startup delays. Ensure piping and downstream components are sized for the flow and that the control logic accounts for the valve’s 3/2 operation and air pilot actuation.
This valve aligns with European regulatory pathways, including European Machinery Directive compliance and PUWER requirements, aiding safe and compliant machine design. While CE marking is commonly pursued for EU equipment, verify with your supplier or installer for project-specific certification needs and ensure proper integration with the control system and safety interlocks.
Maintenance focuses on seal condition and actuator response. The nitrile elastomer seals and zinc alloy body provide robust durability in standard plant environments, reducing unplanned downtime. ROI is driven by smoother startups, lower peak pressures, and extended service life of downstream components due to controlled pressure rise and dump operations.
