D31FCE02DC1NB70 proportional servo valve ，parker
- Brand: Parker/派克
- Product Code: D31FCE02DC1NB70
- Availability: 100
General Description
Series D*1FC pilot operated proportional directional valves come in 4 sizes:
D31FC NG10 (CETOP 5)
D41FC NG16 (CETOP 7)
D91FC NG25 (CETOP 8)
D111FC NG32 (CETOP 10)
The digital onboard electronics is situated in a robust metal housing, which allows usage under rough environmental conditions.
The nominal values are factory set. The cable connection to a serial RS-232 interface is available as an accessory.
The innovative integrated regenerative function into the A-line (optional) allows energy saving circuits for differential cylinders. The hybrid version can be switched between regenerative mode and standard mode at any time.
Features
• Progressive flow characteristics for precise adjustment of flow rate.
• Low hysteresis.
• High dynamics.
• High flow capacity.
• Center position monitoring optional.
• Energy saving A-regeneration optional
• Switchable hybrid version optional.
Further literature about the opportunities of energy savings and more functional details of the integrated regeneration is available on request at Parker HVD Technical Service.
