Feature → Business Impact → Application: The Olympian Plus P68F-NGL-NNN uses a aluminium body with nitrile elastomers to deliver a durable, lightweight solution that reduces fatigue and maintenance costs in high-cycle environments. This translates to lower total cost of ownership for packaging lines and material handling systems, while maintaining precise pressure control for sensitive downstream equipment. Feature → Business Impact → Application: With a solenoid pilot and spring return actuation, the valve offers fast, repeatable opening and controlled dump sequences, minimizing startup shocks and enabling smoother line starts on conveyers and pick-and-place cells. This is crucial for high-speed production lines where timing is critical. Feature → Business Impact → Application: The 3/2 valve operation, combined with a high flow rate of 147 dm3/sec (312 scfm), supports rapid pressure equalization and efficient venting, improving cycle times in pneumatic clamping and gripping applications across automation platforms. Feature → Business Impact → Application: The without-yoke port option and compatible Yoke assemblies (Y68A-6GN-N1N, Y68A-6GN-N2N) simplify installation and retrofit projects, reducing downtime and enabling easy integration with existing manifolds and control rails. Feature → Business Impact → Application: Operating pressure of 3–10 bar and ambient temperature range -20 to 50 °C ensure reliable performance in harsh factory environments, providing predictable behavior in blow-melt tooling, packaging equipment, and CNC automation setups. Feature → Business Impact → Application: The Olympian Plus lineage and aluminium body facilitate heat dissipation and corrosion resistance in demanding environments, supporting longer service intervals and safer maintenance windows for industrial pneumatic systems.
