There are many factors affecting the price of electric butterfly valve, such as valve diameter, medium pressure, valve body material, valve plate material, valve stem material, valve seat material, valve structure, valve and pipe connection, and electric head control mode and power supply voltage and other factors.
With the development of electric valve, there are many well-known valve enterprises at home and abroad to produce electric valve, electric butterfly valve is an important executive unit in the field of industrial automation control.It belongs to a variety of electric valves and electric regulating valves.Widely used in textile, power plant, petrochemical, heating and cooling, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection and other fields.This product can be used as a cut-off valve, control valve and check valve in piping systems.Complete manual control device, electric or pneumatic transmission device, can meet the specific conditions of different working conditions.Meet the most stringent quality requirements, can be very durable application.Especially in the metallurgical steel, shipbuilding industry, has a very high visibility.
Electric butterfly valves are suitable for applications requiring flow regulation.Because the butterfly valve in the pipeline pressure loss is relatively large, about three times the gate valve, so in the choice of butterfly valve, should fully consider the impact of the pipeline system by the pressure loss, but also should consider the closure of the butterfly plate under the pipeline medium pressure robustness.In addition, it is important to consider the temperature limitation of the resilient seat material at high temperatures.Butterfly valve structure length and overall height is small, open and close fast, and has good fluid control characteristics, butterfly valve structure is most suitable for the production of large diameter valves.When the butterfly valve is required for flow control, the most important thing is to choose the correct size and type of butterfly valve, so that it can work properly and effectively.The center line butterfly valve usually, in the throttling, the adjustment control and the mud medium, requests the structure length to be short, opens and closes the speed to be quick (1/4 turns).Low pressure cut-off (small pressure difference), it is recommended to choose butterfly valve.In the two-position regulation, shrink mouth to channel, low noise, cavitation and gasification phenomenon, a small amount of leakage to the atmosphere, with abrasive medium, can choose the butterfly valve.In special working conditions, throttle regulation, or strict sealing requirements, or severe wear, low temperature (cryogenic) and other working conditions when using the butterfly valve, it is necessary to use a special design of metal seal belt adjustment device, three eccentric or double eccentric special butterfly valve.
Operating conditions on the site, determines the selection of butterfly valve specifications, thus determining the price of the butterfly valve.Therefore, the specific price of the butterfly valve or to see the use of the unit mining requirements.
