Wafer butterfly valve is one of the more common valve types in industrial pipelines. The butterfly valve itself has a relatively small structure. You only need to put the butterfly valve in the middle of the flanges at both ends of the pipeline, and use stud bolts to pass through the pipeline flange and the wafer butterfly valve lock. If it is tight, the fluid medium in the pipeline can be controlled. It is especially suitable for places with narrow space or short distance between pipelines. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has a relatively high Good flow control characteristics.
The wafer butterfly valve relies on the motor of the electric actuator to drive the valve shaft of the butterfly valve to rotate, and the valve shaft drives the butterfly plate to rotate 90° to realize the opening and closing of the valve. It can be used for cutting off and adjusting the flow. The electric actuator is equipped with an end limit switch, which can automatically cut off the circuit at the end. At the same time, in order to ensure the safety of the project, it is equipped with an electric overload protection device and a signal light indicator.
