1. Before installing manual butterfly valves, they should not be thrown away at will. They should be placed in a cool, dry, and ventilated environment and covered to avoid dust and other debris that may affect their later use.

Installation requirements for manual butterfly valves

2. Before installing on the pipeline, it is necessary to calibrate the pipeline and ensure that the positions of the pipelines at both ends are consistent without deviation. Otherwise, if the manual butterfly valve is installed in case of deviation in the pipeline, it will cause tension or rupture on the valve body.

3. In addition to correcting the pipeline, there is also a preparatory work before installation, which is to clean the manual butterfly valve and its pipeline to ensure the cleanliness of the valve and pipeline, otherwise it will affect the sealing effect of the valve.

4. Manual butterfly valves require frequent manual operation. So the installation position of manual butterfly valves is also very particular. The valve installation position must be convenient for personnel to operate and maintain in the future. It has been proven that the best location for installing manual valves is around 1.2 meters from the operating floor. Valves installed outdoors should be covered with some covers to prevent adverse weather from affecting the valve.

5. When installing, the butterfly plate of the manual butterfly valve must be in the closed state to avoid collision and damage between the butterfly plate and the pipeline flange, which may affect the sealing performance.

6. After installation, debugging should be carried out. If the manual butterfly valve experiences opening and closing faults during use, the cause should be identified and the fault eliminated. Knocking, prying, or brute force should not be used to forcibly open and close.

The installation requirements for manual butterfly valves are actually very simple, so we need to pay attention to the details after the valve is purchased. Of course, the safety of pipelines and the service life of valves depend on the correct selection and configuration
