Key Points of Installation and Use

1. Read this instruction carefully before installation, and check valve type, size and technical parameters.

2. It is strictly forbidden to Weld flanges after installing valves. The valve installation distance reserved from the pipeline shall be appropriate, and gaskets shall be added on both sides of the flange.

3. The center of the two pipelines and the center of the valve diameter should be coaxial, the flange surface should be flat, and the flange surface should not be allowed to have larger bias, so as to ensure the clamping and normal operation of the valve.

Tightening bolts should be uniform and symmetrical.
