Norgren P68F-8GD-PFN Olympian Plus soft start valve - IP65
Part Number: P68F-8GD-PFN
Quick Summary
Norgren P68F-8GD-PFN is a soft start dump valve for controlled downstream pressure in compressed air systems. Engineers often battle startup surges and noncompliant equipment during line start. It supports European Machinery Directive compliance and PUWER, with IP65 sealing for harsh environments, plus solenoid pilot/spring return. Designed for OEMs and maintenance teams, it offers reliable startup control, high flow, and easy integration with G1 port systems. By meeting clean startup requirements, it minimizes downtime and extends service life of downstream equipment. In busy production lines, the compact aluminium body and sealed design simplify installation and reduce mounting complexity. This combination supports faster commissioning and ongoing regulatory alignment.

FAQs
Start by planning for a compact layout using the recommended wall bracket (18-001-979) or yoke assemblies (Y68A-8GN-N1N / Y68A-8GN-N2N). Connect the G1 port to the main supply line and wire the solenoid pilot for remote operation. Use the Rc1/8 gauge port for monitoring if needed. The unit’s aluminium body and sealed plug IP65 rating simplify installation in demanding environments.
Operating pressure is 3 to 10 bar (44–145 psi), with a high forward flow of 147 dm3/sec or 312 scfm. It is a 3/2 valve operated by a solenoid pilot with spring return, suitable for controlled ramping during start-up in compressed air circuits. Port size is G1, gauge port Rc1/8, enabling easy diagnostics and connection options.
Yes. The P68F-8GD-PFN supports compliance through controlled start-up performance, helping to meet European Machinery Directive requirements and PUWER guidelines. Its IP65 sealing and robust build reduce the risk of noncompliance due to environmental exposure, making it well-suited for automated lines that require safe, repeatable startup sequences.
The valve features IP65 protection with a sealed plug, offering dust and water ingress resistance in challenging environments. It is part of the Olympian Plus range, designed for industrial use in Germany, and supports CE-related compliance for European applications through its rugged, certified construction.
The aluminium body and nitrile elastomers simplify maintenance and resist oil, dust, and mild chemicals common in production environments. The robust design reduces downtime and extends service life of downstream equipment, delivering lower lifecycle costs and faster ROI through higher uptime and more predictable start-ups.
