Products
| AQ type electric actuator 1. (Turning angle < 360 degrees) - suitable for butterfly valves, ball valves, plug valves, etc. The rotation of the output shaft of the electric actuator is less than one week, i.e. less than 360 degrees, and usually 90 degrees to realize the opening and closing process control of the valve. This kind of electric actuator is divided into two types: direct connection type and base crank type according to the different installation interface methods. Direct connection: It refers to the direct connection between the output shaft of the electric actuator and the valve stem Base crank type: refers to the form in which the output shaft is connected with the valve stem through the crank 2. Control mode of electric actuator: (1) Split structure (commonly known as ordinary type) (2) Integrated structure (commonly known as integral type): integral switching type and integral adjustment type 3. According to the requirements of the use environment and explosion-proof level, the electric device of the valve can be divided into: ordinary type, outdoor type, flameproof type, outdoor flameproof type, etc |

| DZW type electric actuator 1. (Angle > 360 degrees) - suitable for gate valves, globe valves, etc. The rotation of the output shaft of the electric actuator is greater than one week, that is, more than 360 degrees, and it generally takes many turns to realize the opening and closing process control of the valve. 2. Control mode of electric actuator: (1) Split structure (commonly known as ordinary type) (2) Integrated structure (commonly known as integral type): integral switching type and integral adjustment type 3. According to the requirements of the use environment and explosion-proof level, the electric device of the valve can be divided into: ordinary type, outdoor type, flameproof type, outdoor flameproof type, etc |
