I. Overview: 

 DCF23S electromagnetic air valve is a dual-coil two way solenoid valve, it pass through the electromagnet (broken) power to open (off) valve end of the pilot hole, the spool to control the fluid medium off. Mainly used in electrical, mechanical, metallurgical, chemical, light industry and other sectors, working in the medium is water, air, oil pipeline to the remote automatic control. 
 Second, characteristics: 

 ? A solenoid coil for long-term work system, drive power is small, the basic heat. 
 ? With manual operating mechanism. 
 ? 3. Differential structure of the media requirements are lower. 
 ? Supply voltage DC220V.
