Stainless steel flanged ball valve installation

1. Install the valve on the pipeline. Either end of the valve can be installed on the upstream end. Valves actuated by handles can be installed anywhere on the pipeline. However, ball valves with gearboxes or pneumatic drives should be installed vertically, that is, installed on horizontal pipes, and the driving device is above the pipe
2. Install a gasket between the valve flange and the pipeline flange according to the pipeline design requirements
3. The bolts on the flange need to be tightened symmetrically, sequentially and evenly
4. Connect the pneumatic pipeline (when using a pneumatic driver)
Inspection after installation of stainless steel flanged ball valve:
1. Operate the driver to open and close the ball valve several times, it should be flexible and free of stagnation, confirming its normal operation
2. Check the sealing performance of the flange joint surface between the pipeline and the ball valve according to the pipeline design requirements
