Light butterfly valve is widely used in the pipeline system of ventilation, environment protection engineering of building material, glass, mining, electricity, light industry, paper-making etc. Adjust and cut off the flow of air media in pipeline according to different control signals.
Structure characters:
Light automatic butterfly valve is welded by quality carbon steel. It is characterized by light weight, simple structure, small resistance loss, nimble operation, definite indication, convenient operation, long using life and free installation etc. Matched with motorized actuator of electronic type and the relevant components, it may be shifted manually and automatically. Electronic control module is applied and no need to be connected with servo amplifier. It will receive the output signal 4～20mA from instrument and computer. Intelligently adjust it and automatically locate it according to the input signal and electric fitting position. It can be controlled by computer programs, CCR or be controlled automatically. It is an ideal equipment to control & operate and adjust the flow automatically.
