Norgren P68F-NGA-NNN Valves & Flow Control - 3-17 bar
Part Number: P68F-NGA-NNN
Quick Summary
The P68F-NGA-NNN soft-start dump valve from Norgren enables controlled pressure release in pneumatic systems. Engineers frequently face startup surges that stress actuators, cause unplanned downtime, and complicate safety compliance. Designed to support European Machinery Directive compliance and PUWER, it helps installers meet regulatory obligations while maintaining consistent cycle times. Its high flow capacity and 3/2 valve performance support efficient startup sequences in packaging, automation, and process applications. Using the recommended yoke assemblies or wall brackets, installation is straightforward in already installed frames, reducing total installation cost. By controlling downstream pressure rise on start-up, it reduces wear and energy use across the line.

Soft-start dump action provides a controlled release of downstream pressure during machine start-up. This mitigates surge forces, protects downstream actuators, and reduces wear on valves and hoses, delivering longer component life for demanding automation lines. Application-wise, it is especially beneficial on high-speed packaging lines and automated conveyors where startup resilience is critical. Air-pilot / spring-return actuation delivers a reliable reset after venting, ensuring repeatable start-up behavior even after rapid cycling. This translates to shorter set-up times, improved line availability, and lower maintenance intervention on busy production floors. Application domains include pick-and-place cells and palletizing stations where consistent re-arm sequences are required. The 3/2 valve operation with a forward flow of 147 dm3/sec (312 scfm) enables fast venting and stable pressure ramp during start-up. The improved flow supports shorter cycle times and increased throughput, reducing bottlenecks in continuous production lines. Typical applications are high-throughput automotive, consumer electronics assembly, and process automation where timing is critical. Constructed with an aluminium body and nitrile rubber elastomers, the valve offers robust durability and chemical compatibility in challenging manufacturing environments. This reduces maintenance costs and minimizes unscheduled downtime caused by wear or seal degradation. Applications span metalworking, plastics processing, and food & beverage lines where reliability and cleanability matter. Without a yoke, the P68F-NGA-NNN provides mounting flexibility, and compatible accessories Y68A-6GN-N1N/N2N (yoke assemblies) plus mounting options 18-001-978/979 (wall brackets) simplify retrofit and OEM integration. This enables faster installation, easier field upgrades, and improved fault-tolerance on evolving automation architectures. Operating pressure from 3 to 17 bar and operating temperature range -20 to 80 °C give broad applicability across environments and equipment families. This versatility supports cross-plant standardization, reduces spare-part inventories, and enhances supplier negotiation power with a single, well-supported solution for multiple lines.

FAQs
The P68F-NGA-NNN is supplied without a yoke. For installation, pair it with compatible yoke assemblies Y68A-6GN-N1N or Y68A-6GN-N2N and mount using wall brackets 18-001-978 or 18-001-979 as needed. Ensure the air supply is clean, and use proper mounting hardware to maintain venting clearances. This approach supports flexible OEM integration and straightforward retrofits in existing frames.
Key operating parameters include a medium of compressed air, an operating temperature range of -20 to 80 °C, and an operating pressure range of 3 to 17 bar. It uses an air-pilot/spring-return actuation with a 3/2 valve configuration and delivers a forward flow of 147 dm3/sec (312 scfm). Material construction features an aluminium body and nitrile rubber elastomers for seals.
Yes. The P68F-NGA-NNN is designed to assist with European Machinery Directive compliance and PUWER, helping machines achieve regulatory alignment through controlled start-up and pressure management. Its performance characteristics are chosen to support safe operation, predictable startup behavior, and the minimization of startup-related risks in automated lines.
Its high flow capacity (147 dm3/sec) and precise pressure ramp enable rapid yet controlled venting during start-up, reducing cycle times and bottlenecks. The 3/2 configuration combined with air-pilot/spring-return actuation provides repeatable behavior across many cycles, improving line throughput and reducing actuator wear on packaging, filling, and sorting lines.
Available accessories include Yoke assemblies (Y68A-6GN-N1N/N2N) for mounting flexibility and mounting hardware 18-001-978/979 (Wall Brackets). These options simplify retrofits and OEM integration, allowing straightforward installation on existing frames and enabling flexible orientation to suit different plant layouts and space constraints.
