Installation Tips For PVC Octagonal Ball Valve

1.1 Preparation before installation

(1) PVC Octagonal Ball Valve front and rear pipelines are ready. The front and rear pipes should be coaxial and the two flange sealing surfaces should be parallel. The pipe should be able to withstand the weight of the ball valve, otherwise the pipe must be equipped with appropriate support.

(2) Purge the front and rear pipelines to remove oil, welding slag and all other impurities in the pipeline.

(3) Check the logo of the PVC Octagonal Ball Valve and find out that the ball valve is intact. The valve was fully opened and closed several times to confirm that it was working properly.

(4) Remove the protective parts on the connecting flanges at both ends of the PVC Octagonal Ball Valve.

(5) Check the valve hole to remove any dirt that may be present, and then clean the valve hole. Even small particles of foreign matter between the seat and the ball may damage the seat sealing surface.

1.2 installation

(1) Install the valve on the pipeline. Any end of the valve can be mounted on the upstream end. Valves driven by the handle can be mounted anywhere on the pipe. However, ball valves with gearboxes or pneumatic drives should be mounted upright, ie on horizontal pipes, with the drive above the pipe.

(2) Install a gasket between the valve flange and the pipeline flange according to the pipeline design requirements.

1.3 Inspection after installation

(1) Operate the drive to open and close the ball valve several times. It should be flexible and without stagnation, and confirm that it works normally.

(2) Check the sealing performance of the flange joint surface between the pipeline and the ball valve according to the pipeline design requirements.
