1. Pilot-oriented mode:Internal pilot or external pilot.
2. Structure in sliding column mode: good tightness and sensitive reaction.
3. Double control solenoid valves have memory function.
4. Internal hole adopts special processing technology which has lttle ttrition friction, low start pressure and long service life.
5. No need to add oil for lubrication.
6. Afiliated manual devices are equipped to facllitate installation and debugging.
7. Several standard voltage grades are optional.
8. Integrate with the manifold to save installation space.
