Norgren P68F-NGH-NFA Soft Start Dump Valve - IP65
Part Number: P68F-NGH-NFA
Quick Summary
P68F-NGH-NFA is a soft-start dump valve that controls downstream pressure during machine startup in automation lines. This helps prevent startup pressure spikes that cause premature wear, energy waste, and unnecessary downtime in automated equipment. It supports CE-marking under the European Machinery Directive and PUWER compliance, with IP65 sealing when used with a sealed plug. By combining a robust aluminium body and nitrile elastomers, it delivers reliable performance in harsh factory environments while enabling cost-effective, compliant pneumatic circuits for downstream pressure control in modern manufacturing.

FAQs
The P68F-NGH-NFA is designed without a yoke for compact installation. If mounting is required, use compatible Yoke assemblies Y68A-6GN-N1N or Y68A-6GN-N2N, and consider the 18-001-979 Wall Bracket for secure enclosure mounting.
The valve provides a flow of 147 dm3/sec (312 scfm) and operates across a pressure range of 3 to 10 bar (44 to 145 psi), suitable for delivering controlled startup pressure in pneumatic circuits.
It aids CE-marking under the European Machinery Directive and helps meet PUWER requirements by controlling startup pressure and reducing risk of equipment shocks, with IP65 sealing to protect against ingress in challenging environments.
The valve uses a solenoid pilot with a spring return in a 3/2 configuration. For maintenance, ensure clean, dry air supply and inspect nitrile elastomer seals; the aluminium body design supports long service life in typical manufacturing conditions.
For retrofit and new builds, leverage Yoke assemblies (Y68A-6GN-N1N/N2N) and the Wall Bracket (18-001-979). The Quietaire MB008B silencer is available for noise reduction in enclosed spaces, aiding quieter operation and compliance with workplace noise limits.
