Some tips must be attention before installation of wafer type butterfly valve:
1. Before starting the installation, use air spray to remove the dirt on the piping.
2. Check carefully whether the valve usage is consistent with its performance specifications such as temperature, pressure.
3. Check the valve passage and sealing surface for debris and remove it in time;
4. After unpacking, the butterfly valve should be installed in time.
5. Wafer item butterfly valve must use special butterfly valve flange.
6. The electric butterfly valve can be installed on the pipeline at any side. For the convenience of maintenance, it is recommended not to install it upside down.
7. When installing the butterfly valve flange, make sure that the flange surface and the sealing rubber are centered, the screws are evenly tightened, and the sealing surface must be intact; if the tightening force of the screws is uneven, rubber protrusions may catch the butterfly plate leaving the disc causes leakage at the valve stem.
