The pinch butterfly valve is especially suitable for the place where the space is narrow or the distance between the pipes is short. When the butterfily

valve is completely opened, the thickness of the buttrfly plate is the only resistance when the medium flows through the valve body, so it can be

reduced very small by the pressure produced by the valve, so it has a better flow control characteristic. Let us explain what are the precautions before

installing buttefly valves.

The careful incident before the clamp butterfly valve placement

1. Before setting up the operation, wash the outer parts of the piping with air spray, and clean the pipes inside with clean water.

2, carefully check whether the valve uiization environment is consistent with its performance, (temperature, pressure)

3, check the valve passage and sealing surface whether there are debris, and real-time cleaning;

4. After opening the didlink valve, the valve should be placed in real time. Do not rotate any fastening screws or nuts on the valve at will.

5. Butterfly valve flanges must be used for clip buttrfly valves.

6, electric butterfly valve can be placed in the pipeline of arbitrary angle, so it is not necessary to reverse placement for maintenance convenience.

7, the butterfly valve flange in the installation must ensure that the flange and seal rubber pair, screw even tighten, the seal face of the buttrfly valve

must be fully ftted; if the screw tightened strength is uneven, the phenomenon of rubber bulge stuck to the butterfly plate, or the buttrfy plate of the

buttrfly valve, will lead to the leakage of the stem.
