SKJ Type High Speed Shutdown Electric Actuator
Our company and Tianjin University developed the electric actuator together, which fills the domestic gap. It was the fastest electric actuator in our country till now. The SKJ product series united with the butterfly valve form the electric valve with fast shutting off performance which is especially suitable for the work situation that needs urgently action.
The high speed series are widely used in the field of cement, the coal gas, agglutinates etc and was highly appraised by users.
SKJ high speed electric actuator is the terminal control unit of an automated control system. It is widely used in the field of power plant, chemical industry, metallurgy, petroleum; especially in the work situation needs urgently action. It forms a complete set of fast shutting off electric valve together with the butterfly valve, which is widely used in the field of roll steel, agglutinate, profession, coal gas and cement industry.
Structure and Theory
SKJ high speed electric actuator is made up of 3-phase motor, reducer, travel route limit and other equipments. When switching on the power, the electric motor impetus output shaft to produce the torque. The travel limit is applied to adjust the output shaft’s rotation degree. The terminal switch has a group normally open contact which is used to show the output signal. When the power shuts off or the limit switch occurs, the brake may rapidly prevent the system’s coasting operation.
