Norgren P68F-8AD-PFA Valve for Safe Start IP65
Part Number: P68F-8AD-PFA
Quick Summary
The P68F-8AD-PFA valve from Norgren is a soft-start dump valve designed to control ramp-up of downstream pressure in pneumatic systems. Engineers often struggle to manage startup surges that stress actuators, valves, and conveyors, risking downtime and component wear. It is CE-compliant under the European Machinery Directive and PUWER-aligned, with IP65 protection when used with the sealed plug. By leveraging the Olympian Plus platform, this valve delivers predictable startups, reduced wear, and regulatory alignment, while enabling fast installation and reliable operation in harsh environments. The combination of high flow, robust construction, and plug-in accessories supports safer, more efficient machine start-ups in modern automation lines.

FAQs
When installing the P68F-8AD-PFA, use the standard Olympian Plus mounting options and ensure a secure 1" PTF connection. Opt for the T68H-8AB-B2N plug-in shut-off valve if you need a coordinated control point, and verify alignment with the Yoke assemblies for proper mounting. Check seal integrity of the IP65 sealed plug to maintain protection in dusty or damp environments. Ensure electrical compatibility with your control system and confirm operating pressure is within 3–10 bar for reliable startup behavior.
The 3/2 valve configuration enables a defined normally closed or energized state, while the solenoid pilot with a spring return provides rapid, repeatable actuation. This combination allows precise pressure ramp control during startup, reducing transient peaks and shortening cycle times. In practice, you gain smoother actuation of downstream components and improved repeatability in automated lines such as packaging, robotics, and handling systems.
Yes, the P68F-8AD-PFA supports CE compliance under the European Machineries Directive and PUWER-related guidelines, reflecting its suitability for regulated industrial environments. The IP65 rating (with sealed plug) further enhances suitability for harsh factory floors, wash-down zones, and outdoor installations. Always verify machine-specific regulatory requirements and perform a site-specific risk assessment during deployment.
This valve excels in industries requiring reliable startup control for pneumatic subsystems, such as packaging, material handling, automation cells, and automotive manufacturing lines. Its high flow capacity supports rapid pressurization, while the robust aluminium body and nitrile elastomer seals tolerate real-world factory conditions. It also pairs well with Olympian Plus accessories for retrofit projects and line expansions.
Maintenance benefits come from durable aluminium construction and nitrile elastomer seals, reducing frequency of seal replacements and corrosion-related downtime. Compatibility with Olympian Plus family components simplifies spares management and retrofit planning, enabling faster uptime and predictable service intervals. The predictable startup performance translates to higher throughput, lower wear, and a favorable total cost of ownership over the valve’s lifecycle.
