Details that should be paid attention to when using butterfly valves
Butterfly valves are especially suitable for places where space is narrow or the distance between lines is short. When the butterfly valve is fully opened, the thickness of the butterfly plate is the resistance when the medium flows through the valve body, so it can be generated by the valve, therefore, the pressure drop is small, so the flow can be better controlled. The following is an introduction to the precautions before installation of the wafer butterfly valve.
Please change carefully before placing the wafer butterfly valve
1. Before starting the installation, please use air spray to remove foreign objects on the pipe, and then clean the inner surface of the pipe with clean water.
2. Carefully check whether the operating environment of the valve matches its performance example; (temperature, pressure)
3. Check whether there are debris in the valve passage and sealing surface, and remove them in real time.
4. The valve should be installed in real time after unpacking, and do not rotate any screws or nuts on the valve at will.
5. Wafer butterfly valves must use special butterfly valve flanges.
6. The electric butterfly valve can be installed on the pipeline at any angle. For easy maintenance, do not install it upside down.
7. When installing the butterfly valve flange, it must be ensured that the flange surface and the sealing rubber are aligned, and the screws are tightened evenly, and the sealing surface of the butterfly valve must be completely installed. If the screws are tightened unevenly, the rubber bumps can get stuck. The disc phenomenon or the disc against the butterfly valve, causing the valve stem to leak.
