10. General Notes
- Direct acting solenoid valves operate from zero pressure up to full rating; pilot operated valves require a minimum ΔP of 0.5 bar.
- Solenoid valves are recommended to be installed horizontally with the coil facing upwards to prevent debris settlement in stem.
- Pulse valves (dust collector) feature exceptionally rapid opening times, maximizing the blast volume of pressurized air.
- Standard coils are designed for continuous 100% duty cycle (ED 100%) operation without thermal damage under rated voltages.
