Precautions for Installing High Pressure Floating Ball Valves

Notes on installing High-Pressure Floating Ball Valves :

1. The maintenance of the electric ball valve includes the preparations before installation, the installation of the electric pipeline ball valve, the inspection after the installation of the electric pipeline ball valve, and the maintenance of the electric pipeline ball valve.

2. The electric ball valve is corroded during use. After metallographic structure analysis, dyeing test face, heat treatment test face, SEM, and other test analysis, it is found that the key factor of material corrosion is that the carbides along the grain boundary in the material are precipitated to form the valve in the chromium-poor area.

3. After the electric ball valve is installed, start the electric pipeline ball valve to open and close several times. The action should be flexible, the force should be uniform, and the ball valve should work normally; sealing performance.

4. In order to ensure that the pipeline at the installation position of the electric ball valve is in the coaxial position, the two flanges on the pipeline should be kept parallel to confirm that the pipeline can bear the weight of the pipeline ball valve. If it is found that the pipeline cannot bear the weight of the pipeline ball valve, the pipeline is equipped with corresponding supports.

5. Install a gasket between the electric pipeline ball valve flange and the pipeline flange according to the pipeline design requirements. The bolts on the flange should be tightened symmetrically, sequentially, and evenly. If the pipeline ball valve adopts electric actuators, complete it according to the instructions. Installation of the power supply.
