These pneumatic directional control valves products -------- pneumatic control valve of LD series solenoid valve and air valve can replace 3V and 4V valves. LD is same dimensions and function as 3V,4V. They are improved from 3V and 4V valves.
The advantage of LD valves:
LD series adopt imported seal.
LD valve shaft is “HARD ANODIZING” Processed.
LD coil have over loading protecting.
