PPH electric ball valve with flange ball valve Working principle
Sanitary valves can be driven by electric or pneumatic actuator, with signal to automatic control the valve open and close. The actuators rotate the discs freely within 90° to open or close or regulate the flow of the medium.

PPH electric ball valve with flange Leakage Class
Soft sealing butterfly valve: Zero leakage
Metal hard seal concentric butterfly valve: 1% leakage
Metal hard seal double/triple eccentric butterfly valve: Zero leakage

Application areas
The ball valve can serve as the isolation and adjustment function of the key parts of the system. It is widely used in pipelines in almost all industrial fields. The applicable media include liquids, gases and granular materials.The main application areas are:
-chemical and petrochemical industry
– Marine Engineering
– gas supply system
– food industry
– Wastewater treatment and water supply and drainage engineering
– Cold storage and HVAC system
– power plants and heating plants

The pipeline before and after the ball valve is ready. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipe should be able to bear the weight of the ball valve, otherwise the pipe must be equipped with proper support. Clean the pipelines before and after the valve to remove the oil, welding slag and all other impurities in the pipeline. Check the mark of the ball valve to find out that the ball valve is intact. Fully open and close the valve several times to verify that it is working properly. Remove the protective parts on the connecting flanges at both ends of the ball valve. Check the valve hole to remove possible dirt, and then clean the valve hole. Even small foreign matter between the valve seat and the ball may damage the seat sealing surface. Install the valve in the pipeline. Either end of the valve can be installed at the upstream end. The valve driven by the handle can be installed at any position on the pipeline. But the ball valve with gear box or pneumatic driver should be installed upright,that is, installed on the horizontal pipeline, and the driving device is above the pipeline. Install a gasket between the valve flange and the pipeline flange according to the pipeline design requirements. The bolts on the flange need to be tightened symmetrically, successively and evenly. Connect the pneumatic line (when using a pneumatic drive). Operate the driver to open and close the ball valve several times. It should be flexible and free of stagnation to confirm its normal operation. Check the sealing performance of the flange joint surface between the pipeline and the ball valve according to the pipeline design requirements.
