Norgren P68F-8GH-PFA Dump Valve - IP65 Certified
Part Number: P68F-8GH-PFA
Quick Summary
The P68F-8GH-PFA dump valve provides controlled downstream pressure during startup for pneumatic systems in industrial machinery. It mitigates surges that stress actuators, reduces cycle life variance, and minimizes unplanned downtime. This design supports CE/Machinery Directive compliance and PUWER, with IP65 protection when used with a sealed plug. Constructed from aluminium with nitrile elastomers, it delivers high flow (312 scfm) across a wide operating window. Compatible with G1 ports, 3/2 operation, and solenoid pilot–spring actuation, it simplifies integration for Olympian Plus installations. Designed for reliability in demanding environments, its IP65 rating ensures resistance to dust and water ingress in factory floors. Engineers benefit from consistent startup performance and straightforward integration with accessories like the T68H-8GB-B2N shut-off valve, enabling faster commissioning and safer operations.

Feature: Medium is compressed air. This standard air medium ensures compatibility with most industrial pneumatic circuits, minimizing contamination risk and simplifying filtration strategies. Application: The P68F-8GH-PFA is well suited for machines in packaging, material handling, and assembly lines that rely on quick, controllable actuation of downstream dampers and cylinders. This translates to fewer air leaks and more predictable cycles. Feature: Operating pressure range of 3–10 bar. Impact: enables consistent startup sequencing and protects downstream devices from pressure spikes, reducing premature wear and energy waste. Application: ideal for startup circuits in presses, conveyors, grippers, and assembly cells where gradual ramp improves cycle reliability. Feature: Actuation and valve topology—Solenoid pilot with spring return; 3/2 valve; Port Size G1; Gauge Port Rc1/8. Impact: provides flexible control to retrofit existing control schemes and supports modular mounting for easy upgrades. Application: retrofits into Olympian Plus installations with simple plug-and-play compatibility. Feature: Materials and protection—Aluminium body, nitrile elastomers; IP65 with sealed plug; Dimensions 241 mm x 190 mm x 147 mm; Weight 3.125 kg. Impact: rugged, corrosion-resistant construction suitable for wash-down environments and long service life; space-conscious footprint simplifies panel integration. Application: ideal for heavy throughput lines and automated equipment in harsh factory settings. Feature: Compliance and compatibility—Part of the Olympian Plus range; supports CE/Machinery Directive and PUWER compliance; compatible accessories include T68H-8GB-B2N, Y68A‑8GN‑N1N, Y68A‑8GN‑N2N, and MB008B silencer. Impact: shorter commissioning times, safer operations, and scalable retrofits. Application: retrofit projects on existing lines migrating to compliant, high-flow pneumatic control.

FAQs
Install the P68F-8GH-PFA on a G1 port using the solenoid pilot, ensuring the Rc1/8 gauge port is accessible for any needed monitoring. Mounting options such as Yoke assemblies (Y68A-8GN-N1N/N2N) or a wall bracket (18-001-979) simplify retrofit. Use the T68H-8GB-B2N plug-in shut-off valve where fast isolation is required. Check IP65 sealing with a sealed plug to maintain protection.
The valve operates over 3-10 bar with a high forward flow of 147 dm3/sec (312 scfm), enabling a controlled ramp that reduces pressure spikes. This results in smoother actuator startup, less stress on downstream cylinders, and faster return-to-cycle times in conveyors, presses, or grippers, while maintaining reliable performance across varying loads.
Yes. The valve is IP65 rated with a sealed plug, and built with an aluminium body and nitrile elastomers for durability in dusty or wet factory environments. Note that while it is washdown-capable, verify chemical compatibility of nitrile elastomers with any aggressive cleaners in your process and avoid explosive atmospheres unless rated accordingly.
The P68F-8GH-PFA supports CE/Machinery Directive compliance and PUWER requirements, aided by the IP65 rating for ingress protection. This helps design engineers meet regulatory risk reduction and safety guidelines for automated equipment, streamline certification processes, and ensure safer startup sequences across European manufacturing environments.
Maintenance is focused on elastomer seal wear and routine inspections of the solenoid pilot and spring return mechanism; replace seals as needed with standard Norgren parts. The unit’s rugged aluminium construction reduces downtime, while controlled startup minimizes energy waste and wear, delivering a favorable return on investment through improved cycle times and longer actuator life.
