Norgren P68F-AGH-NPN Valve - Olympian Plus Dump
Part Number: P68F-AGH-NPN
Quick Summary
Norgren P68F-AGH-NPN valve provides controlled pressure start/dump for pneumatic circuits in automation lines. Engineers often wrestle with startup shocks that stress cylinders, valves, and conveyors, leading to downtime and accelerated wear. The design supports CE marking and Machinery Directive compliance, and it can help satisfy PUWER requirements for safer equipment operation. Its compact Olympian Plus platform offers high flow with reliable solenoid pilot operation, enabling faster startups without compromising control. This valve integrates smoothly with standard mounting and common air-handling components, delivering both performance and long-term cost savings for OEMs and maintenance teams.

Feature 1: Soft-start dump functionality reduces downstream pressure spikes during machine startup. Business Impact: Protects cylinders, conveyors, and seals, lowering maintenance costs and extending equipment life. Application: Ideal for automated packaging lines and pick-and-place systems where startup surges threaten uptime. Feature 2: 3/2 valve operation with solenoid pilot and spring return provides reliable, fail-safe actuation. Business Impact: Improves line reliability and safety, reducing unscheduled downtime. Application: Suitable for indexing valves and actuator control in harsh environments. Feature 3: High flow capacity (147 dm3/s / 312 scfm) enables rapid system turn-on and fast venting. Business Impact: Shortens cycle times and increases throughput in high-speed automation. Application: Effective in process lines requiring quick pressure equalization. Feature 4: Robust construction with aluminium body and nitrile elastomers offers durability and resistance to oil-free compressed air. Business Impact: Lower replacement costs and longer service intervals. Application: Compatible with standard industrial air supplies and routine maintenance. Feature 5: Wide operating range and port compatibility (3–10 bar, G1-1/4, Rc1/8) simplify integration. Business Impact: Reduces design changes and installation time, improving time-to-value. Application: Works with common mounting brackets and accessories for streamlined deployment. Feature 6: Regulatory alignment (Machinery Directive and PUWER) supports compliant machine commissioning. Business Impact: Minimizes regulatory risk and speeds time-to-market. Application: OEMs upgrading legacy lines or designing new equipment for European markets.

FAQs
The valve uses a G1-1/4 port size for main flow and a Rc1/8 gauge port for monitoring or control, aligning with standard industrial components. Mounting is compatible with common wall brackets such as 74504-50 and 18-001-978, ensuring quick, secure installation without custom hardware. This supports straightforward integration into existing air-handling layouts.
Key specs include a flow of 147 dm3/s (312 scfm) and an operating pressure range of 3 to 10 bar (44 to 145 psi). The valve operates in a 3/2 configuration with solenoid pilot and spring return, delivering reliable actuation and fast venting during startup or shutdown sequences.
Yes. The Olympian Plus platform provides controlled pressure rise and a rapid dump on startup, minimizing downstream shocks to feeders, conveyors, and pneumatic cylinders. Its 3/2 configuration and robust materials support continuous operation in high-demand packaging environments while maintaining safety and process integrity.
The valve is designed to assist machine builders in achieving CE marking and Machinery Directive compliance and can help existing equipment meet PUWER requirements. This translates to safer equipment operation, clearer documentation, and reduced regulatory risk across European installations.
Choose the robust aluminium body with nitrile elastomers for durability in oil-free compressed air systems. Pair with standard silencers and plug-in accessories as needed, and rely on familiar mounting hardware to minimize downtime during upgrades. Regular inspection of ports and seals, combined with planned preventive maintenance, extends service life and lowers total cost of ownership.
