Norgren P68F-6GL-PPN Valve for Compressed Air IP65
Part Number: P68F-6GL-PPN
Quick Summary
Norgren P68F-6GL-PPN is a soft start dump valve for compressed air systems, used to control downstream pressure during startup. Engineers frequently struggle with pressure spikes, startup transients, and unplanned downtime that reduce line efficiency and tool life. The device supports European Machineries Directive compliance and PUWER requirements while delivering IP65 protection for challenging environments. Its G3/4 port, RC1/8 gauge port, and Olympian Plus platform provide flexible integration with existing lines, while high flow and precise control boost throughput. In short, it helps ensure safer, more efficient startups and a faster return on investment for automated pneumatic systems.

Feature → Business Impact → Application: The P68F-6GL-PPN combines a solenoid pilot with spring return actuation to deliver controlled pressure ramp during startup, reducing shock loads and wear on downstream components. This translates to lower maintenance costs, fewer unplanned shutdowns, and longer life for valves, regulators, and actuators in high-cycle packaging and automation lines. Application: packaging machines and assembly lines benefit from smoother acceleration, improved cycle timing, and enhanced line reliability in environments where rapid, repeatable startups are critical. Feature → Business Impact → Application: Aluminum body with nitrile rubber elastomers provides robust corrosion resistance and seal integrity, cutting downtime from seal failures and extending service intervals. Application: hostile manufacturing floors and wash-down areas where IP65 protection is essential. Feature → Business Impact → Application: 3/2 valve operation with G3/4 ports enables straightforward retrofits and modular system design, reducing installation time and integration risk. Application: retrofit projects on legacy pneumatic rigs or Olympian Plus configurations. Feature → Business Impact → Application: 147 dm3/sec (312 scfm) flow capacity supports high-demand tooling without bottlenecks, increasing throughput and process stability. Application: high-speed robotic pick-and-place or CNC tooling lines. Feature → Business Impact → Application: Rc1/8 gauge port allows precise pressure measurement and monitoring, enabling better process control and diagnostics. Application: control loops and sensor feedback integration in automated lines.

FAQs
Mount the valve on a stable base or Olympian Plus mounting kit, connect the G3/4 main line to the valve inlet, and thread the RC1/8 gauge port into the pressure sensing line. Use the wall bracket 18-001-979 or yoke assemblies if needed for vibration resistance. Ensure the system is depressurized, seal plugs are in place, and follow the installation guide for torque specs.
Key specs include a 3/2 valve operation, G3/4 port size, operating pressure 3–10 bar (44–145 psi), flow 147 dm3/sec (312 scfm), and actuation via solenoid pilot with spring return. Gauge port is Rc1/8. This combination supports rapid response with reliable startup control across typical pneumatic lines.
Yes. The P68F-6GL-PPN aids European Machineries Directive compliance and PUWER requirements by providing controlled startup and protected operation. It carries IP65 protection, which helps ensure safe performance in challenging environments and supports regulatory alignment during system integration.
The valve operates from -20 to 50 °C and is rated IP65 with sealed plug. It features an aluminum body and nitrile rubber elastomers for seals, offering robust durability in industrial settings, including wash-down areas and dusty environments. Dimensions are 241 mm height, 190 mm length, 147 mm width, and weight 3.125 kg.
The soft-start action reduces startup surges, minimizing wear and tear on downstream components and shortening cycle times. This leads to lower maintenance costs, reduced downtime, and improved overall equipment effectiveness (OEE). The robust build and compatibility with Olympian Plus systems also simplify upgrades and retrofits, accelerating time-to-value.
