Norgren P68F-8GL-PPA Olympian Plus Dump Valve - IP65
Part Number: P68F-8GL-PPA
Quick Summary
Norgren P68F-8GL-PPA Olympian Plus dump valve provides controlled start-up pressure for pneumatic systems in automation environments. This helps machine builders avoid startup shocks that can damage actuators or compromise safety. Designed to support CE conformity with the European Machinery Directive, IP65 protection with sealed plug, and PUWER compliance considerations, the valve helps you meet regulatory requirements with confidence. The unit delivers a deliberate pressure ramp and high forward-flow capacity, enabling reliable sequences from clutching to actuation without overshoot. By integrating with standard G1 port fittings and the 3/2 valve topology, it fits neatly into existing boards and control logic, reducing integration risk while boosting system efficiency and uptime.

FAQs
Begin by mounting the valve using standard Norgren hardware; connect the upstream supply to the G1 port and the downstream line to the work circuit. Wire the solenoid pilot for control and ensure supply pressure falls within 3–10 bar. Refer to the installation guide for wiring diagrams and CAD data to ensure proper orientation and leakage-free seals.
The P68F-8GL-PPA supports controlled start-up sequencing that reduces risk of startup shocks, aiding compliance with CE Machinery Directive and PUWER requirements. IP65 protection with a sealed plug enhances suitability for harsh environments, while aluminium construction and nitrile elastomers meet industry durability expectations, contributing to safer, compliant equipment operation.
Important specs include the 3–10 bar operating pressure range, 147 dm3/sec (312 scfm) flow, 3/2 valve configuration, G1 port size, Rc1/8 gauge port, operating temperature of -20 to 50 °C, and IP65 protection with sealed plug. These parameters define startup behavior, control precision, and integration compatibility with standard air-network fittings.
Yes. The Olympian Plus family provides plug-in options like T68H-8GB-B2N shut-off valves and Yoke assemblies (Y68A-8GN-N1N / Y68A-8GN-N2N), plus wall brackets (18-001-979). These accessories simplify installation, enable secure mounting, and reduce the number of distinct parts required for retrofit or new-build projects.
Routine checks should verify seals and connections for signs of wear or leakage. The aluminium body and nitrile elastomer seals are robust in typical plant environments, but periodic inspection of the gauge port and port seals is advised. If components show wear, replace seals and re-torque fittings to maintain IP65 protection and peak performance.
