Norgren P68F-8GC-PBA Dump Valve - IP65 (sealed plug)
Part Number: P68F-8GC-PBA
Quick Summary
The P68F-8GC-PBA is a Norgren dump valve with soft start control for startup pressure in pneumatic systems. Engineers often struggle to meet EU machinery directives and PUWER while avoiding dangerous pressure surges at startup. It supports CE marking and EU Machinery Directive alignment, and delivers IP65 protection with a sealed plug for harsh environments. With a robust aluminium body, G1 port and 3/2 valve operation, it enables reliable, scalable automation across lines.

Feature → Business Impact → Application: Soft-start control via the solenoid pilot and spring return gradually opens the valve to limit downstream surge. This reduces peak pressures, minimizes wear on cylinders and seals, and shortens restart times. Application focuses on automated lines, pneumatic presses, and assembly cells where a controlled start improves reliability and component life. Feature → Business Impact → Application: Aluminium body with nitrile elastomer seals delivers long-term durability and compatibility with common factory lubricants. Business impact: robust IP65 protection with a sealed plug protects electronics and internals from dust and moisture, reducing field faults. Application: outdoor installations, dusty workshops, and other harsh environments common in material handling and packaging lines. Feature → Business Impact → Application: Standard G1 thread main port and Rc1/8 gauge port enable straightforward integration with existing manifolds, cylinders, and sensors. Impact: simplifies retrofits and minimizes downtime during installation. Application: retrofit projects and new-build lines using 3/2 valve configurations, enabling quick alignment with current piping schemes and control logic. Feature → Business Impact → Application: High flow capacity at 147 dm3/s (312 scfm) provides rapid pressure control and responsive startup behavior. Impact: improves cycle efficiency and reduces process variation, especially in high-speed packing, robotic pick-and-place, and clamp-and-release operations. Application: systems requiring fast, predictable pressure ramp and reliable dump performance under 3–10 bar supply. Feature → Business Impact → Application: Broad accessory compatibility including T68H-8GB-B2N plug-in shut-off valve, Yoke assemblies (Y68A-8GN-N1N/N2N), wall brackets, and quieting silencers (MB008B) enables turnkey installation. Impact: reduces sourcing time and installation complexity, while maintaining a tidy, modular skid. Application: upgrades, retrofits, or new lines where a complete package simplifies compliance and reduces project risk.

FAQs
The P68F-8GC-PBA uses a G1 port main connection and an Rc1/8 gauge port for instrumentation. Mounting is supported by Yoke assemblies (Y68A-8GN-N1N/N2N) or a wall bracket (18-001-979). For plug-in integration, consider the T68H-8GB-B2N shut-off valve accessory and the MB008B silencer to reduce noise. These options simplify retrofits and help maintain system integrity during upgrade projects.
Key specifications include a 3/2 valve operation with G1 main port and Rc1/8 gauge port, flow of 147 dm3/s (312 scfm), operating pressure range of 3–10 bar, and an operating temperature range of -20 to 50 °C. The device uses aluminium body construction with nitrile elastomer seals, suitable for compact, high-demand pneumatic systems.
Yes. The unit is designed to support EU Machinery Directive alignment and CE marking, helping meet regulatory expectations for safe startup control and electrical enclosure integrity. Its IP65 protection with a sealed plug further supports compliance in dusty or moist factory environments, reducing the burden of regulatory audits for new lines or refurbishments.
Available accessories include Yoke assemblies (Y68A-8GN-N1N/N2N) for secure mounting, a wall bracket (18-001-979) for space-constrained layouts, and a Quietaire silencer MB008B to reduce noise. The T68H-8GB-B2N plug-in shut-off valve assists fast integration into existing pneumatic manifolds, enabling rapid, low-effort retrofits.
Expect reduced startup surge and cycle wear, leading to longer actuator life, lower maintenance costs, and improved machine uptime. The valve’s IP65 rating and CE alignment support regulatory compliance, while its compatibility with standard porting and accessories enables faster installations and fewer project delays, delivering a favorable total cost of ownership in automated lines.
