Before installation, clean the inside and outside of the pipe to ensure no sundries; Carefully check whether the use of the valve is consistent with its performance specifications; Install the valve in time after opening, do not invert; The screw shall be tightened before installation, and the sealing surface shall be completely fitted.
Wafer butterfly valve is one of the most common types of valves in the industrial pipeline, wafer butterfly valve itself is a small structure, only need to put the butterfly valve into the middle of the flanges at both ends of the pipeline, with studs through the pipeline flange and clamp butterfly valve lock, you can control the pipeline fluid medium. Double flange wafer butterfly valve is especially suitable for small space or short distance between pipelines, butterfly valve in the fully open position, the thickness of the valve plate is the only resistance when the medium flows through the valve body, so the pressure drop through the valve is very small, so it has a good flow control characteristics.
