description1
Product Documents
Product feature
1. Internally piloted structure.
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 little attrition friction,low start pressure and long service life.
5. No need to add oil for lubrication.
6. Install in the side plate with the surface upward,which can be used by directly connecting with the actuators.
7. Affiliated manual devices are equipped to facilitate installation and debugging.
8. Several standard voltage grades are optional.

[Note1] PT thread.G thread and NPT thread are available.
[Note2] Once lubricated air is used.continue with same medium to optimise valve life span. Lubricants like ISO VG32 or equivalent are recommended.
[Note3] The maximum actuation frequency is in the no-load state.
[Note4] Equivalent orifice S and Cv are all calculated from the flow rate data.
Maintenance Notice
1. Be sure to check up the valves before handling.
2. Before installation,please confirm the voltage is up to the mustard,and connection and direction of the air fl ow are right.
3. Notice to be dustproof. It's best to install a silencer or speed control silencer in front of solenoid valve.
4. Metal grain,dust and oil stain in pipes and fittings must be washed neat before connected.
