As factory automation and industrial automation fields are growing, the pneumatic solenoid valves used in these fields are becoming more important as well.  As safety is the top priority in the pneumatic system, An-Hyup Control has devleoped a dual valve to enhance the safety level.  The dual solenoid valve of An-Hyup Control has passed several tests on vaious features flow features, dynamic performance, temperature increase, insulation resistance, inner voltage, power consumption, air leakage, surge, gressure resistance and duravility performed by the Korea Institute of Industral Technology of the Ministry of Commerce, Industry and Energy.  The dual solenoid valve also paased the feature test and the technical review process of the Korea Institute of Industral Technology.  To manufacture better quality products, An-Hyup Control has co-developed and applied devices for the flow feature test and the dynamic performance test with Korea Institute of Industral Technology as meeting the Korean Industrial Standard.


1. Cut off air and remove air in the tank
2. Loose four wrench bolts and remove the valve head part
3. Loose the wrench bolt on the bottom of Astal (Polyoxymethylene) cover and take out Astal and spring.
4. If pushing the shaft after taking out the T-letter urethane, Astal and shaft are separated.  Remove foreign materials in the
    disassembly course and then remove foreign materials inside of the body by opening Air
5. Remove the foreign material stuck to the parts before assembly and apply some of oil and then assembly it in the reverse order of
    the above sequence.
6. If you want reassembly, follow backward of the explanation above.
    T-urethane must be adhered closely, so that there is no air leakage.
