A the DKX type electric valve control box and I produced the Z-type, electric control box of Q-type and DQ superimposed supporting the use of valve actuator for opening and closing of the control valve can be used for site individually controlledor remote centralized control. A common type, outdoor type and explosion proof. Common type was divided into a drawer and Wall-two structures.

     The control box drawer under the following conditions normal working altitude height of not more than 1000 meters. The ambient temperature is not higher than +50 ℃ and no less than -60 ℃ air relative humidity less than 85%. Enough to corrode metal and damage the insulation gas and conductive dust explosion hazard media. Control box, electrical performance and life depends on the AC contactor, thermal relay, the intermediate relay, and terminals. To provide special requirements
