Remote-Controlled Float Valve Remote Float Valve

The composite high-speed air inlet and exhaust valve is a special air inlet and exhaust control device for water supply pipelines, which is widely used in the pipe network systems of various waterworks and in various water supply fields. The term "composite" refers to a valve that has the functions of both large-hole and small-hole air inlet and exhaust. When filling an empty pipeline with water, the large exhaust hole automatically and rapidly discharges the air inside the pipeline at a high speed. When the pressurized water is flowing inside the pipeline, a small amount of gas will accumulate at the top of the exhaust valve, and the small hole automatically discharges this part of the gas outside the pipeline. When negative pressure is generated inside the pipeline, it can automatically intake air at a high speed to break the vacuum, so as to prevent the pipeline from buckling and being damaged due to the negative pressure.
