Norgren P68F-AGB-NNN Olympian Plus dump valve - G1-1/4
Part Number: P68F-AGB-NNN
Quick Summary
Norgren P68F-AGB-NNN is a high-performance dump valve used for controlled pressure release in pneumatic systems across automated tooling and packaging lines. Design teams contend with startup surges, downstream overpressure, and the risk of nonconformance when machines ramp up. This Olympian Plus unit supports CE compliance under the European Machinery Directive and PUWER requirements, helping you mitigate risk during commissioning and routine maintenance. Constructed with an aluminium body and nitrile elastomers, it delivers a clean, high-flow dump with a 3/2 valve configuration and air‑pilot/spring return actuation for reliable operation. Compact dimensions and compatible ports simplify retrofits and expansions in existing lines, delivering measurable reductions in start-up time and energy waste.

The P68F-AGB-NNN uses a high-flow dump valve designed for rapid, controlled pressure release, enabling a gentler startup sequence and reduced stress on downstream components. Business impact: smoother line ramp, fewer pressure spikes, and lower wear on actuators, which translates to higher equipment uptime and lower maintenance costs. Application: packaging machines, tool changers, and automated lines where startup surges previously caused downtime. The valve’s air-pilot/spring-return actuation provides flexible control and safe fail-safe behavior, ensuring a predictable shutdown in power-loss scenarios. Business impact: improved safety margins and simpler integration with existing control logic. Application: critical lines requiring dependable fail‑safe operation. Port size and gauge port compatibility (G1-1/4 and Rc1/8) support standard piping and diagnostic access, reducing retrofit time and enabling easier field servicing. The aluminium body and nitrile elastomer seals balance strength with lightweight handling, improving vibration resistance and corrosion tolerance in harsh factory floors. Business impact: longer service life with lower total cost of ownership. Operating pressure from 3 to 17 bar and a wide temperature range (-20 to 80 °C) extend the device’s applicability across multiple industries, including automotive and packaging, while the 3/2 valve topology delivers precise control of downstream pressure. Application: versatile deployment in varied tool actuation and clamping sequences. Additional benefits come from the compact footprint (165 mm × 200 mm × 108 mm) and a weight around 3.05 kg, which simplify enclosure fitment and mounting in retrofit projects. Business impact: easier installation, reduced enclosure modifications, and faster time-to-value. Accessories such as the MB008B heavy‑duty silencer, M/P15737 electrical plug, and T68C-BGB-B2N shut-off valve further streamline installation and maintenance, lowering installation risk and enabling quieter operation on busy lines.

FAQs
Begin by confirming supply pressure within 3–17 bar and ensure compatible piping for G1-1/4 ports. Mount the valve in the correct flow direction and connect the gauge port Rc1/8 for diagnostics. Use the included accessories where applicable, such as the MB008B silencer or the M/P15737 plug assembly, to simplify installation and reduce noise. Verify actuator alignment and perform a leak test after mounting.
Plan for a 3–17 bar operating range and -20 to 80 °C temperature tolerance to cover typical factory environments. Expect a 3/2 valve operation with air-pilot/spring return actuation and a maximum flow around 147 dm3/s (312 scfm). The aluminium body and nitrile elastomer seals support durability, while a compact footprint (165×200×108 mm) aids retrofit projects.
Yes. This valve is designed to assist compliance with the European Machinery Directive and PUWER, helping you meet safe startup practices and equipment commissioning requirements. While it supports regulatory alignment, ensure correct system integration, documentation, and periodic inspection to maintain ongoing compliance across your manufacturing process.
Included accessories include MB008B heavy‑duty silencer, M/P15737 electrical plug with cable gland, and T68C-BGB-B2N plug-in shut-off valve to simplify wiring and noise attenuation. The device also provides Rc1/8 gauge port access for diagnostics. For best results in surface-mounted enclosures, plan for secure mounting hardware and compatible fittings for G1‑1/4 piping.
Conduct routine checks on the nitrile elastomer seals and inspect for signs of wear or leakage in the aluminium body. Expect reduced startup surges, lower energy use, and improved line uptime, which translate to a faster return on investment. The unit’s robustness supports long service life in demanding environments with minimal intervention.
