Electric butterfly valve


Electric butterfly valve belongs to the electric valve and electric control valve in a species. Electric butterfly valve connections are: Flange and wafer; electric butterfly valve seal are: rubber seals and metal seals. Electric butterfly valve through the power signal to control the butterfly valve switch. The product can be used as piping system shut-off valve, control valve and check valve. With manual control device, in the event of power failure, you can temporarily use manual operation, will not affect the use.

With the development of electric valve, there are many well-known domestic and foreign valve manufacturers to produce electric valves, electric butterfly valve is an important industrial automation control unit. It belongs to a variety of electric valves and electric control valve. Widely used in textile, power plants, petrochemicals, heating and cooling, pharmaceuticals, shipbuilding, metallurgy, light industry, environmental protection and other fields. The product can be used as piping system shut-off valve, control valve and check valve. Complete manual control, electric or pneumatic actuator, to meet the specific conditions of different conditions. Meet the most stringent quality requirements, can be very long-lasting applications. Especially in the metallurgical steel, shipbuilding industry, has a very high visibility.

Electric butterfly valve for flow control applications where needed. As the butterfly valve pressure loss in the pipeline is relatively large, about three times the gate valve, so the choice of butterfly valve, piping system should be fully taken into account the impact of pressure loss, but also consider the pressure on the butterfly plate to withstand the pressure off the firm Sex. In addition, the operating temperature of the elastomeric seat material must also be considered at high temperatures. Butterfly valve structure length and overall height is small, open and close fast, and has good fluid control characteristics, the butterfly valve structure principle is most suitable for the production of large-caliber valves. When a butterfly valve is required for control flow, it is of paramount importance that the correct size and type of butterfly valve be chosen so that it functions properly and effectively. Midline butterfly valves typically require short lengths of construction and fast opening and closing (1/4 turn) in throttling, conditioning and mud media. Low-pressure cut-off (pressure difference is small), the recommended choice of butterfly valve. In the two-bit regulation, narrow channel, low noise, cavitation and gasification phenomenon, a small amount of leakage to the atmosphere, with abrasive media, you can choose butterfly valve. In special operating conditions, throttling regulation, or require strict sealing, or severe wear and tear, cryogenic (cryogenic) conditions such as the use of butterfly valves, the need to use special design metal seal with the adjustment device to three eccentric or
double eccentric Butterfly valve.
