Norgren P68F-NGH-PBA Dump Valve - IP65 Sealed
Part Number: P68F-NGH-PBA
Quick Summary
Norgren P68F-NGH-PBA is a soft-start dump valve that controls startup pressure in pneumatic automation systems. Startup surges can lead to pressure spikes, component wear, and unplanned downtime, particularly on packaging lines and automated assemblies. It supports European Machinery Directive compliance and PUWER, with IP65 sealing (sealed plug option) for demanding environments. Built with an aluminium body and nitrile elastomers, the 3/2 valve uses solenoid pilot with spring return to deliver predictable startup behavior. In practice, this means easier integration, improved uptime, and lower lifecycle costs for OEMs and end users alike.

Feature → Business Impact → Application: Soft-start dump function provides a controlled ramp on downstream pressure during machine start-up, reducing pressure spikes and mechanical shock, which extends cylinder seals and actuators—ideal for automated packaging lines and robotic assemblies that require smooth, reliable start-up. Feature → Business Impact → Application: High forward flow capacity of 147 dm3/sec (312 scfm) enables rapid actuator movement without overshoot, improving cycle times while maintaining downstream control in high-speed pick-and-place and material-handling lines. Feature → Business Impact → Application: IP65 rating with sealed plug offers environmental protection against dust and wash-down exposure, lowering maintenance needs in general manufacturing, automotive assemblies, and electronics packaging environments. Feature → Business Impact → Application: Aluminium body with nitrile elastomer seals provides toughness with reduced weight, delivering corrosion resistance and easier installation for OEMs across factory floors. Feature → Business Impact → Application: PortSize Without Yoke plus available Yoke assemblies (Y68A-6GN-N1N/N2N) and Wall Bracket 18-001-979 enable flexible mounting and retrofits on existing manifolds, frames, and control cabinets. Feature → Business Impact → Application: Wide operating range −20 to 50 °C and 3–10 bar support compatibility with most factory air systems, minimizing configuration issues and supporting a broad range of automation lines.

FAQs
The P68F-NGH-PBA uses a port configuration rated 'Without Yoke' and can be mounted with the Wall Bracket 18-001-979. If a yoke is needed later, you can add Yoke assemblies Y68A-6GN-N1N or Y68A-6GN-N2N. For best results, ensure proper sealing and alignment with the sealed plug option and follow the datasheet installation guidelines.
Expect a 3/2 valve operation with solenoid pilot and spring return, a regulated 3-10 bar operating range, flow of 147 dm3/sec (312 scfm), and an aluminium body with nitrile elastomer seals. The device maintains stable startup pressure across typical factory air supplies, improving cycle times while protecting downstream components.
Yes. Its controlled pressure ramp minimizes surges, aiding precision in robotic pick-and-place and packaging equipment. The aluminium body provides durability, IP65 sealing helps in dusty or wash-down environments, and the 3/2 configuration aligns with common pneumatic circuits used in high-speed automation.
The valve assists compliance with the European Machinery Directive and PUWER. It features IP65 sealing (with sealed plug) to withstand challenging factory conditions, supporting regulatory and safety requirements in many industries without compromising performance.
By delivering a controlled startup, it reduces mechanical wear, minimizes downtime from pressure spikes, and improves cycle efficiency. Its compatibility with common Norgren accessories and flexible mounting options streamline retrofits and new installs, delivering lower maintenance costs and faster payback on automation projects.
