1. Before installation, it is necessary to carefully check whether the logo and certificate of the butterfly valve meet the requirements of use, and should be cleaned after verification.
2. The butterfly valve can be installed at any position on the equipment pipeline, but if there is a transmission device, it should be installed upright, that is, the transmission device must be vertical to the position of the horizontal pipeline, and the installation position is conducive to operation and inspection.
3. The connecting bolts between the butterfly valve and the pipeline should be tightened several times in the diagonal direction during installation. The connecting bolts should not be tightened at one time to prevent the flange connection from leaking due to uneven force.
4. When opening the valve, turn the handwheel counterclockwise, when closing the valve, turn the handwheel clockwise, and rotate it in place according to the opening and closing indicators.

Valves that have been kept for a long time should be regularly cleaned, dried, and coated with anti-rust oil. Blind plates should be used at both ends of the valve to protect the flange sealing surface and prevent impurities from entering the inner cavity.
8. Transportation of the valve: The valve should be packaged well when shipped, and should be packaged according to the contract to ensure that parts are not damaged or lost during transportation.
9. Warranty of the valve: The valve is put into use within one year, but not more than 18 months after delivery. If it is indeed due to material defects, unreasonable manufacturing quality, unreasonable design and damage in normal use, it will be confirmed by the quality inspection department of our factory.
