Flange Butterfly Valve

The installation of flange turbine butterfly valves requires special attention to the following points: firstly, at least 10 times the diameter of the pipeline should be left on both sides of the pipeline for future maintenance and disassembly; Secondly, the installation of cast iron butterfly valve should follow the normal flow direction of the fluid and mark the fluid flow direction on the valve body; Again, the installation position of the butterfly valve should be horizontal or tilted no more than 5 degrees to avoid affecting the sealing and opening/closing of the butterfly valve; In addition, during the installation process, it is necessary to ensure that the butterfly valve flange and the pipeline flange are parallel and correspond one-to-one, and then tighten them with bolts to ensure a firm installation; Finally, appropriate clamp and bolt specifications should be selected based on the type, diameter, medium, etc. of the butterfly valve, and relevant pre tightening force checks should be conducted to ensure that the butterfly valve is installed in the correct position and avoid leakage or damage.
