Pneumatic Wafer Type Butterfly Valve
Introduction:
Pneumatic wafer butterfly valve, as the name suggests, adopts the method of wafer clamping, which clamps the butterfly valve between the flanges at both ends of the pipeline, and then uses a set of bolts to pass through the bolt holes to fix it.
Working Principle:
The pneumatic wafer butterfly valve is powered by the compressed air source of 0.4-0.7MPa, and drives the valve stem to drive the disc plate to rotate 0-90 degrees in the valve body to achieve the operation control of the butterfly valve fully open and fully closed. The pneumatic wafer butterfly valve can be equipped with a valve for the actuator according to the requirements of the working conditions, and input the relevant signal of 4-20mA, so as to control the opening of the butterfly valve disc, and realize the pressure, flow, temperature, liquid level and other parameters of the medium in the pipeline. The percentage of precise adjustment. Pneumatic wafer butterfly valve can be used not only for local control in industrial automatic control system, but also for remote centralized control. It is the preferred system device for industrial pipeline applications.
