Application of Electric Butterfly Valve in Hydropower Plant

Electric butterfly valves play a vital role in hydropower plants. They are easy to open and close, labor-saving, and have little fluid resistance. They have simple structure, small size, and light weight. They can achieve good sealing under low pressure and have good adjustment performance.

With the upgrading and transformation of production equipment in many hydropower plants, the old manual gate valves in the room have been gradually upgraded to electric butterfly valves. They are easy to open and close, labor-saving, and have little fluid resistance. They have simple structure, small size, and light weight. They are easy to use and save a lot of manpower and material resources for hydropower plants.

Electric butterfly valves are important implementation modules in the industrial automation control industry. They belong to a type of electric valves and electric regulating valves. They are widely used in textile industry, power plants, petrochemical equipment, heating and cooling, pharmaceuticals, shipbuilding, metallurgy, light industry, environmental protection and other industries. They can be used as cut-off valves, control valves and check valves for pipeline systems.

The butterfly valve has a small structural size and overall height, faster opening and closing speed, and has good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making large-diameter valves. When a butterfly valve is required to control flow, the most important thing is to correctly select the specifications and types of butterfly valves so that they can work correctly and effectively.

Centerline butterfly valves are usually required to have short structural specifications and faster opening and closing speeds (1/4 turn) in throttling, adjustment control and mud media. For low pressure cutoff (small pressure difference), butterfly valves are recommended.

Butterfly valves can be used in double-position adjustment, constricted channels, low noise, cavitation and gasification, small leakage to the atmosphere, and abrasive media.

When operating butterfly valves under special working conditions, such as throttling adjustment, strict sealing requirements, obvious damage, low temperature (deep cold), etc., it is necessary to operate a three-eccentric or double-eccentric special butterfly valve with a specially designed metal seal with adjustment equipment.
