Norgren P68F-NGH-NPA Dump Valve - IP65
Part Number: P68F-NGH-NPA
Quick Summary
Norgren P68F-NGH-NPA dump valve provides controlled pressure relief for pneumatic start-up in packaging and automation lines. Across machines, sudden startup pressure spikes can wear seals, increase energy use, and trigger unexpected downtime. This device supports compliance with the European Machinery Directive and PUWER, and features IP65 protection for tough environments. Operating from 3 to 10 bar and driven by a solenoid pilot with spring return, the P68F-NGH-NPA offers 3/2 valve operation and a high flow of 147 dm3/sec (312 scfm) to meet demanding lines. This combination delivers safer startups and straightforward installation, with optional Yoke assemblies and mounting accessories to fit evolving production layouts.

Feature to Business Impact to Application: The P68F-NGH-NPA operates on compressed air, enabling seamless integration into standard pneumatic circuits within automated lines, reducing integration time and simplifying control logic for engineers. Operating across -20 to 50 °C and a 3-10 bar range supports versatile deployment in environments from clean rooms to manufacturing floors, delivering reliable performance in variable conditions. With solenoid pilot / spring return actuation and 3/2 valve operation, it provides fail-safe startup sequencing, improving safety and predictable cycle times on assembly lines. The impressive flow rating of 147 dm3/sec (312 scfm) shortens fill times for downstream actuators, enabling faster tool changes and higher throughput. Aluminium body and nitrile elastomer seals deliver durability and chemical resistance, while IP65 protection protects against dust and water ingress during washdowns. Optional Yoke assemblies (Y68A-6GN-N1N/N2N), wall mounting (18-001-979), and MB008B silencer simplify installation and noise management, reducing maintenance overhead and total cost of ownership in retrofit projects. Designed for compatibility with Norgren accessories and third-party manifolds, it streamlines retrofits and expansion of existing lines, supporting scalable automation strategies in manufacturing and packaging sectors.

FAQs
The P68F-NGH-NPA is designed for straightforward retrofits with standard pneumatic manifolds. It uses a port size without a yoke, with optional Yoke assemblies Y68A-6GN-N1N and Y68A-6GN-N2N for quick mounting. Use the Wall Bracket 18-001-979 for wall installation where space is constrained. For noise reduction and exhaust management, hang MB008B silencer. Ensure a secure 24 VDC or appropriate control signal to the solenoid pilot and verify IP65 sealed plug connections to maintain enclosure integrity during washdown or dusty environments.
Operating pressure range is 3-10 bar (44-145 psi) with a flow of 147 dm3/sec (312 scfm), enabling rapid charging of downstream lines while controlling surge. The 3/2 valve configuration supports simple logic in start-up sequences, reducing ramp time and mechanical stress. These specs translate to shorter cycle times and improved throughput in automated lines, especially when starting multiple actuators or cylinders in parallel. Proper power supply and clean, dry air further optimize performance and longevity.
Yes. The Olympian Plus P68F-NGH-NPA is purpose-built for automated start-up control in packaging and general industrial automation. Its soft-start/dump functionality moderates downstream pressure during startup, protecting seals and downstream components. The aluminium body and robust seals provide durability in high-demand packaging environments, while the IP65 rating supports washdown-ready operation. Its compact size and optional mounting accessories make it adaptable for retrofit projects and CNC machine integration where controlled air release improves reliability.
The P68F-NGH-NPA offers IP65 protection with a sealed plug for harsh environments and washdown readiness. It aligns with European Machinery Directive guidelines and PUWER for equipment safety and usability. The valve is manufactured in Germany, reflecting high European engineering standards. These certifications and origin details help simplify regulatory paperwork and procurement for EU-based facilities and provide confidence in long-term service and support.
The valve uses an aluminium body and nitrile elastomer seals, delivering durability against corrosion and chemical exposure while maintaining a predictable seal life. Its robust construction reduces unplanned downtime, and the availability of mounting accessories and silencers minimizes retrofit complexity. Routine maintenance is straightforward: inspect seals, verify IP65 seals, and confirm solenoid operation. Overall, these factors contribute to lower maintenance costs, longer service intervals, and faster payback in production environments relying on reliable pneumatic startup control.
