Norgren P68F-8GG-NPA Olympian Plus Dump Valve - IP65
Part Number: P68F-8GG-NPA
Quick Summary
P68F-8GG-NPA is a high-performance dump valve designed to safely ramp downstream pressure in pneumatic startup for packaging and automation lines. Engineers often struggle with sudden start-up shocks that cause wear, vibration, and unplanned downtime. CE compliance under the Machinery Directive, PUWER alignment, and IP65 protection (with sealed plug) help you meet European regulations. As part of the Olympian Plus family, it integrates with standard compressed-air systems to improve startup reliability and overall machine uptime. OEMs and maintenance teams gain predictable performance, easy installation with compatible mountings, and lower lifecycle costs through reduced wear and energy waste. This combination supports faster compliance audits and minimizes downtime in mixed production environments.

The P68F-8GG-NPA uses a robust aluminium body and nitrile elastomer seals to deliver durable operation in challenging environments, translating to reduced maintenance cycles and lower total cost of ownership for automated lines. High forward flow of 147 dm3/sec (312 scfm) enables rapid yet controlled venting during startup, improving cycle times and reducing tool wear on downstream actuators while maintaining safe ramping for sensitive cylinders. The solenoid pilot with spring return offers a fail-safe control path, ensuring the valve returns to a safe state during power interruptions, which minimizes unexpected machine stops and protects operators during commissioning or fault conditions. IP65 protection with a sealed plug provides reliable performance in dusty or washdown environments, lowering field failure rates and the need for frequent resealing. Compatibility with Y68A yoke assemblies and standard Mountings simplifies installation on existing machines, accelerating retrofit projects and minimizing downtime. The Olympian Plus series is designed for European compliance and robust industrial use, making it suitable for packaging lines, automated assembly, and conveyor systems where startup shocks negatively impact throughput. In practice, these features translate to measurable improvements in uptime, energy efficiency, and regulatory compliance across demand-rich manufacturing settings.

FAQs
Installers should mount the valve using compatible mounting options such as Y68A-8GN-N1N or Y68A-8GN-N2N yoke assemblies, ensuring a solid, vibration-resistant fit. Connect to a G1 supply line with a Rc1/8 gauge port for monitoring. Use the IP65-rated sealed plug to protect the electrical connection in dusty or washdown environments. Verify the 3/2 valve orientation aligns with downstream actuators for proper startup ramp behavior.
Key metrics include a 3–10 bar operating range, 147 dm3/sec (312 scfm) flow for rapid but controlled venting, and a 3/2 valve configuration that delivers a predictable pressure ramp to downstream cylinders. The solenoid pilot / spring return provides fail-safe actuation, ensuring consistent shutdown behavior that minimizes shock loads during power loss or fault conditions.
Yes. The valve supports CE-related compliance under the European Machinery Directive and PUWER considerations, and it carries IP65 protection with a sealed plug, suitable for moderately harsh industrial environments. This combination helps fulfill regulatory expectations for automated equipment while preserving safe operation during startup sequences.
Applications with sensitive downstream actuators, where startup shocks can cause wear or misalignment, gain the most. Examples include cylinder-based clamping, pick-and-place grippers, and feed systems on packaging lines. The device’s controlled ramp, high flow, and rugged build reduce cycle time variability and improve overall line stability in automated environments.
Owners can expect lower maintenance costs due to a durable aluminium body and nitrile seals that resist wear in regular use, plus fewer unplanned downtime events from power interruptions thanks to a fail-safe design. The valve’s compatibility with common mountings enables faster retrofits, reducing installation time and boosting line availability, which translates to a favorable ROI over the equipment’s life cycle.
