Norgren P68F-8GC-PFA Dump Valve - IP65 Sealed
Part Number: P68F-8GC-PFA
Quick Summary
P68F-8GC-PFA is a high-capacity dump valve that provides soft-start control for pneumatic systems. Engineers often face abrupt startup pressure spikes that stress downstream cylinders and shorten component life. This IMI Norgren design supports CE alignment with the European Machinery Directive and IP65 protection with a sealed plug. Its 3/2 valve operation and high-flow capacity translate to faster startup cycles, reduced energy use, and easier compliance testing for regulated environments. For OEMs and maintenance teams, the Olympian Plus line offers reliable integration with G1 port size, standard mounting options, and established spare-part availability to minimize downtime.

FAQs
For immediate compatibility, connect to a G1 port system and use the Rc1/8 gauge port for instrumentation. The valve is designed to work with standard Olympian Plus accessories such as T68H-8GB-B2N plug-in shut-off valves and Yoke assemblies (Y68A-8GN-N1N / N2N). Ensure supply pressure is within 3–10 bar and that mounting follows the 190 mm × 147 mm × 241 mm footprint for straightforward retrofits.
Key factors are flow capacity (147 dm3/s or 312 scfm), operating pressure range (3–10 bar), and the 3/2 valve configuration. The combination of soft-start action and high forward flow reduces surge-induced load on downstream cylinders and accelerates venting, leading to shorter cycle times and more consistent process control.
Yes. The P68F-8GC-PFA is designed for controlled start-up in high-throughput environments. Its soft-start reduces mechanical stress on grippers and actuators, while its compact footprint and standard porting simplify integration into packaging lines, conveyors, and light robotics, delivering reliable performance with minimal rework.
The design supports CE alignment with the European Machinery Directive and meets IP65 sealing standards with a sealed plug, helping manufacturers satisfy PUWER and related regulatory expectations. This combination offers a clear pathway to regulatory compliance during machine upgrades or new equipment builds.
Nitrile rubber elastomer seals and an aluminium body are chosen for durability and resistance to common industrial lubricants. Regular inspection of seals and connection integrity is advised; spare parts are readily available. The valve’s fast startup and high flow contribute to productivity gains, reducing cycle times and improving overall return on investment.
