Butterfly valve electric actuators are made open-close circular disc and with the valve rod rotation to open and close and regulating fluid channel of a valve .Butterfly valve electric actuators is not only simple structure, small volume, light weight, low material consumption, installation size is small, and the drive torque is small, easy operation, quickly, and at the same time also has a good flow regulating function and close the seal characteristics, in the field of large and medium size, the use of low and medium pressure, butterfly valve is the dominant form of the valve.
As anti-corrosion application of synthetic rubber and ptfe, butterfly valve electric pneumatic actuators performances are improved, and satisfy different working conditions. In recent years, the metal sealing butterfly valve electric actuator has developed rapidly, with high temperature resistant, resistant to low temperature, strong corrosion resistance, strong erosion resistance, high strength alloy material in the application of butterfly valve, make the metal sealing butterfly valve electric actuators under high temperature, low temperature, strong erosion have been widely used, such as operating conditions and partly replace the cut-off valve, gate valve and ball valve.
Structure features of butterfly valve electric actuator: butterfly valve electric actuator has simple structure, small volume, light weight, small installation size, the butterfly valve electric actuator is small and quick, and it can do a 90 ° reciprocating rotary switch with low driving torque. The butterfly valve electric actuator is used for truncation and connection. Regulate medium in pipe has good flow control characteristics and close the sealing performance.
Nominal pressure or stress level: PN1.0-4.0 MPa, ANSI CLASS 150-300 lb, JIS10-20 k
Nominal diameter or size: DN40-2000
Connection mode: flange connection, the connection to the clamp, the butt welding and lugs on the clip
Applicable temperature: 196 ℃ ~ 700 ℃
Oil leakage phenomenon of traction substation main transformer butterfly valve electric actuator is a difficulty of substation maintenance staff. Our company staff after many experiments, made a special small tools. A 20 mm inner diameter steel pipe end processing of two small tanks, steel tube into the butterfly valve after two small tanks just stuck the nut inside the butterfly valve, so, and butterfly valve electric actuator for internal loose nut oil leakage at this difficult problem is solved.
When the butterfly valve electric actuator is in the fully open position, the butterfly plate thickness is medium. It flows through the body when the only resistance is high. Thus produced by the valve pressure drop is small. The butterfly valve electric actuator has good flow control characteristics. Butterfly valve electric actuator has a seal and metal seal with two kinds of seal type. We can embed the elastic sealing valve and sealing ring in the body and also attach them to the butterfly plate peripheral. So we believe that the butterfly valve electric actuator is of great convenience to all the users.
