Feature → Business Impact → Application: The Olympian Plus soft-start dump valve features a solenoid pilot with spring return, delivering a controlled ramp of downstream pressure. This reduces shock loads on downstream cylinders and valves, improving uptime in high-cycle packaging and assembly lines. Application: start-up sequences for pneumatic actuators in automated lines. Feature → Business Impact → Application: High forward flow capacity (147 dm3/sec, 312 scfm) enables rapid charging of downstream circuits without compromising controlled ramping. Application: quick, reliable actuation of parallel cylinders in material handling systems. Feature → Business Impact → Application: Aluminium body with nitrile elastomer seals provides robust resistance to vibration and oils, increasing service life in harsh factory floors. Application: long-term reliability in continuous operation. Feature → Business Impact → Application: IP65 rating with sealed plug protects electronics in dusty environments, reducing maintenance and unplanned downtime. Application: outdoor or dirty-room installations. Feature → Business Impact → Application: G1 port and Rc1/8 gauge port support easy integration into existing piping and diagnostic setups, simplifying installation and testing. Application: retrofit into legacy Norgren systems with minimal downtime. Feature → Business Impact → Application: Compliance support for Machinery Directive and PUWER, reducing engineering risk and accelerating approvals. Application: new line builds or major machine refurbishments. Feature → Business Impact → Application: Compatibility with the Olympian Plus range ensures scalable expansion, stock commonality, and faster spares provisioning.

FAQs
Begin by confirming a G1 main port connection for the valve body. Mount the unit in a suitable enclosure or frame, connect the downstream piping to the G1 outlet, and use the Rc1/8 gauge port for inline testing and diagnostics. Ensure the solenoid is wired per local electrical standards and check the IP65 seal with the sealed plug during commissioning.
Key specs include operating pressure from 3 to 10 bar (44 to 145 psi), medium: compressed air, flow capacity of 147 dm3/sec (312 scfm), valve operation 3/2, actuation via solenoid pilot/spring return, and materials of aluminium body with nitrile rubber elastomers. Gauged port is Rc1/8, and the unit is IP65 rated with sealed plug.
Yes. The P68F-8GC-PFN provides a controlled pressure ramp with high forward flow, reducing startup shocks while enabling rapid actuation of downstream cylinders. Its robustness, 3/2 valve configuration, and IP65 protection make it well-suited for high-cycle packaging lines where reliable, repeatable start-ups are essential.
The valve supports European Machinery Directive compliance and PUWER considerations, aiding approvals for new machines or retrofits. IP65 protection helps meet protection requirements in dusty or damp environments, while the robust aluminium body and nitrile seals contribute to long-term compliance with operational safety standards.
Benefits include reduced startup downtime, lower risk of downstream damage, and longer service life from a rugged aluminium body and seals. Maintenance focuses on periodic inspection of seals and wiring, with readily available spare parts within the Olympian Plus family, ensuring quick swaps and minimizing total cost of ownership.
