Norgren P68F-NGH-PFN Dump Valve - Olympian Plus 3/2 IP65
Part Number: P68F-NGH-PFN
Quick Summary
P68F-NGH-PFN dump valve provides controlled start-up pressure relief for pneumatic systems in automated machinery. Engineers often wrestle with pressure surges during startup that can stress components, cause tool wear, or trigger unplanned downtime. By design for the Olympian Plus family, it supports compliance with the European Machinery Directive, PUWER, and IP65 sealing in rugged environments. With robust aluminium construction and a solenoid pilot/spring return actuation, the device delivers reliable performance while minimizing maintenance. That combination translates to faster commissioning, reduced lifecycle costs, and streamlined integration for OEMs and maintenance teams.

FAQs
The P68F-NGH-PFN is designed without a yoke by default, but it is compatible with Y68A-6GN-N1N and Y68A-6GN-N2N yoke assemblies. For retrofit projects, verify mounting clearance and ensure the wall bracket 18-001-979 is available. This enables quick, tool-friendly installation with minimal downtime.
The valve provides a controlled increase of downstream pressure during startup, reducing pressure spikes that could stress seals and cylinders. With a 3/2 configuration and solenoid pilot/spring return, startup timing is predictable, improving cycle times and reducing wear on downstream components.
Yes. It supports European Machinery Directive compliance and PUWER guidance through controlled startup behavior and robust IP65-rated enclosure. This helps OEMs demonstrate regulatory alignment while maintaining machine uptime and safety in industrial environments.
Maintenance is straightforward due to the aluminium body and nitrile elastomer seals, which resist common contaminants. Regular inspection of the solenoid pilot, seals, and any Michelin-rated connectors is advised, and the IP65 seal reduces ingress risks in dusty or damp environments.
By delivering reliable startup control, reducing downtime, and enabling easier compliance, the valve lowers maintenance labor, extends component life, and minimizes unplanned stops. The modular design and available mounting options also support faster installations and retrofits, improving ROI for OEMs and service teams.
