1、 Purpose:

DKZ-BYM explosion-proof integrated straight stroke electric actuator is an electric actuator that adopts the integrated structure of intelligent digital locator module independently developed by our factory. It is the execution unit in the DDZ electric unit combination instrument, which receives the signal of the adjustment unit and automatically completes the adjustment task. It is widely used in industries such as power, chemical, petroleum, metallurgy, building materials, and light industry.

The DKZ-BYM electric actuator adopts an explosion-proof structure with the explosion-proof mark of dIIBT3, and can be used in specified explosive gas environments (refer to GB3836.1-2000 "General Requirements for Electrical Equipment Used in Explosive Gas Environments" for the scope of use).

DKZ-BYM electric actuator, with on-site manual function, can be operated on site.
