Product Details
Product description
The electric ball valve is provided with the same rotating 90 degree lifting action, with a circular through hole or a channel through its axis. The ratio of the spherical surface and the channel port should be such that when the ball is rotated 90 degrees, the inlet and outlet should be all spherical, thereby cutting off the flow. Electric ball valves only need a very small torque can be closed tight. Full equality of the inner cavity of the valve body to provide a very small resistance, through the flow channel. It is generally considered the most suitable for direct use, but the recent development has been designed so that it has a throttle and control flow. Electric ball valve is now in the oil, natural gas, medicine, food, water and electricity, nuclear power, electricity, water supply and drainage, heating, metallurgy and other industries to be widely used, is the key to the construction of national defense machinery products. It occupies a lot in the market share, mainly because the electric ball valve strong function, small volume, reliable performance, flow capacity, light and pleasant, remote control, such as a variety of reasons, electric ball valve is not only throttle, cut-off, cutting, breaking, good products or flow regulating system of preferred products.

Storage and maintenance:
1 valves should be stored in a dry and ventilated place. The application of lid port channel.
2 long-term storage of the valve should be regularly checked and cleaned, in particular, to clean the surface of the valve seat sealing surface to prevent damage.
3 if stored for more than 18 months, the valve should be tested before installation, and make a good record.
4 electric valve repair and assembly, the sealing performance test should be carried out.
Installation and maintenance:
1 before installation to confirm the valve identification (such as models, nominal diameter, nominal pressure, material) is based on the requirements of the pipeline system identification.
2 carefully check the valve's channel and sealing surface before installation. If you have any goods, shall be cleaned.
3 before installation, make sure that all the bolts are tightened.
4 before installation, make sure the packing is pressed.
