Feature: Medium is compressed air, a standard utility across automation lines, enabling a compact, maintenance-friendly actuation path. Business Impact: uses existing plant air, avoids hydraulic oil contamination, and minimizes lifecycle maintenance. Application: ideal for start-up sequencing on packaging lines, assembly cells, and automated conveyors where predictable ramp is critical. Feature: Operating temperature range -20 to 50 °C ensures reliable performance across factory floors, cold mornings, and warm shifts. Business Impact: reduces performance drift and unexpected downtime due to temperature extremes. Application: suitable for OEM builds and retrofits in environments with variable ambient conditions. Feature: Operating pressure 3-10 bar with G1 port and Rc1/8 gauge port; Valve operation 3/2; Solenoid pilot / spring return. Business Impact: delivers controlled upstream-to-downstream pressure rise and precise actuation timing, improving cycle consistency and throughput. Application: used for safe startup sequences in pneumatic cylinders and clamping devices. Feature: Flow 147 dm3/s (312 scfm); Materials: aluminium body, nitrile elastomer seals; IP65 with sealed plug. Business Impact: high-flow capacity reduces pressure drop, enabling faster tool cycling; rugged construction withstands washdowns and frequent disconnections. Application: recommended for heavy-use lines in automotive, packaging, and automation cells. Feature: Compatibility and installation ease with accessories like MB008B silencer and M/P19063 electrical plug; mounting options such as 74504-50 Wall Bracket. Business Impact: simplifies installation, reduces noise, and supports seamless retrofits with existing Olympian Plus components. Application: ideal for OEMs needing modular, scalable valve systems with minimal wiring and plumbing changes. Feature: Compliance and reliability support; reduces downtime and supports CE/Machinery Directive alignment and PUWER compliance. Business Impact: delivers safer start-up sequences and easier maintenance planning. Application: suitable for regulated industries including packaging, food & beverage, and general manufacturing.

FAQs
Install the unit on a G1 port manifold, connect the compressed-air supply within 3-10 bar, and attach the Rc1/8 gauge port to the monitoring line. Wire the solenoid pilot to the control circuit per the installation guide, and use the sealed plug option to preserve IP65 integrity in washdown environments. Refer to compatible accessories like MB004B silencer for noise suppression.
Key specs include a 3/2 valve operation, flow of 147 dm3/s (312 scfm), operating pressure of 3-10 bar (44-145 psi), operating temperature range -20 to 50 °C, port size G1, gauge port Rc1/8, aluminium body with nitrile elastomer seals, and IP65 rating with sealed plug. These parameters enable reliable startup sequencing across standard pneumatic systems.
Yes. The Olympian Plus dump valve is designed to assist compliance with the European Machinery Directive and PUWER. Its IP65 sealing with sealed plug supports washdown environments, while the 3/2 valve configuration provides controlled startup sequences that reduce risk and help certify safe, compliant equipment for OEM and end-user installations.
IP65 means the valve is dust-tight and protected against water jets from any direction when used with the sealed plug. This makes it suitable for standard washdown lines and damp factory spaces, reducing ingress risks and extending service life in harsh environments.
The aluminium body and nitrile elastomer seals deliver long service life with minimal downtime. The high flow enables faster cycles, lowering throughput time and energy waste. Compatibility with silencers and mounting brackets facilitates easy retrofits and predictable maintenance planning, contributing to improved return on investment for automated production lines.
