1.2.6. Additional special selection code.

Y02: adjust the maximum number of turns according to the user's requirements;

Y40: other non-standard special connection type;

H01: with space heater (5.6kΩ, 220V AC).

Note: when adding special selection code, add "- Z" after standard code and special selection code. For example, the model of DZW1000 with space heater is DZW1000-x-x-x-ZH01; the model of DZW1000 with space heater and non-standard special connection is DZW1000 - × - Z × - × - ZH01 + Y40.

1.3. Structural features

DZW series valve electric device consists of six parts, namely special motor, reducer, control mechanism, hand electric switching mechanism, hand wheel components and electrical part. According to the user's requirements, it can be equipped with corresponding control module, and also can choose the non-invasive valve electric device with built-in control module. The motor motion is transmitted to the output shaft after the reduction of spur gear and worm gear pair to form the multi rotation motion of the output shaft, and the multi rotation motion of the output shaft is transmitted to the control mechanism after the increase of the speed of the bevel gear pair. At the same time, due to the influence of the reaction force, the worm also moves in the axial direction while rotating, and the torque signal is transmitted to the control mechanism through the crank, and the valve position is output by the control mechanism And torque signal.
