Wafer butterfly valve is especially suitable for places with narrow space or short distance between pipelines. When the butterfly valve is fully opened, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so it can be produced by the valve Therefore, the pressure drop is very small, so it has better flow control characteristics. Explain to you what are the precautions before installing the wafer butterfly valve.
Careful changes before the placement of the wafer butterfly valve
1. Before the installation starts, clean the piping with air spray to remove foreign objects, and clean the inner surface of the piping with clean water.
2. Carefully check whether the valve utilization environment is consistent with its performance examples; (temperature, pressure)
3. Check whether there is debris on the valve channel and sealing surface, and clean it up in real time;
4. The valve should be installed in real time after unpacking, please do not turn any fastened 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 the convenience of 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, the screws are evenly tightened, and the sealing surface of the butterfly valve must be completely fitted; if the screw tightening force is uneven, the rubber bumps will be stuck. The phenomenon of the butterfly plate, or against the butterfly plate of the butterfly valve, causing leakage at the valve stem.
