1, electric gate valve: the valve body with a flat, perpendicular to the flow direction of medium plate lifting to realize open and close.

characteristic: good in sealing, fluid resistance small, open and close force is small, wide range of USES, also have certain flow adjusting performance, generally applicable to large diameter pipeline.

2, electric ball valves, a the hole in the middle of the sphere is used as the Industrial Valves core, * rotating sphere to control the opening and closing of hair.

characteristics: simple structure in gate valve, small volume, fluid resistance small, can take the place of gate valves.

3, electric butterfly valves: open and close to a disc, valve body, a fixed shaft rotate.

features: simple structure, small dimension, light weight, valve suitable for the production of large diameter.

because the seal structure and the material has problem, so is only used for low pressure, used for conveying water, air, gas, and other media.

electric butterfly valve plate and ball valve core are around its axis rotation movement; Gate valve plate is along the axis of lifting movement; Butterfly Industrial Valves and gate valve can adjust the flow rate through the opening; Ball valve is not easy to do this.

1, electric ball valve sealing surface is spherical

2, electric butterfly valve sealing surface is circular cylinder is

3, electric gate valve sealing surface is flat.
