The Moog D680 Series Proportional valve is now optionally available with a closed-loop controlled, D633 Direct Drive Valve as a pilot stage.The advantages of the new pilot stage option are a higher resistance against contamination, optimized dynamics and improved repeatibility. For more details, please refer to the updated product catalog.
Key features :
- Optimized design of valve bodies for high rated flow
- High energy efficiency due to D633 pilot valve with low internal leakage
- Low range of minimum pilot pressure required
- Integrated amplifier and control electronics for high functional flexibility
- Excellent dynamic response due to high natural frequency of pilot stage
- Different fail-safe options available allowing the best fit to application
- Optionally available: new pilot valve with integrated electronics and position control of the pilot valve
