There are two kinds of electric butterfly valve
types: switch type and intelligent type. Match butterfly valve with the DSR actuators, input control signals (4 ~ 20mADC or 1 ~ 5VDC) and single phase power supply, thus the electric butterfly valve’s operation can be controlled. The electric butterfly valve owns strong function, small volume, reliable performance, simple mating and large flow capacity. It is light and convenient which especially is suitable for sticky medium including particle and fiber properties. At present, the valve is widely used in food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power industries and other industrial automatic control system.
Here are some performance parameters of electric butterfly valve as follows:
1. Electric butterfly valve
Nominal size: 50-1200mm.
Nominal pressure: PN1.0, 1.6 and 2.5 MPa.
Connection: JB/T78-59 jb79-59 clamp flange connection.
Materials: HT200ZG25IZG1Cr18Ni9/ZG0Cr17Ni12Mo2 lining PTFE metal hard seal.
Medium temperature: Room temperature type: -20oc ~ + 200oc.
Heat type: -40oc ~ + 450oc.
2. Components inside the valve
(electric butterfly valve data)
Valve core forms: valve plate.
Flow feature: linear or equal percentage characteristics.
Material: HT200ZG25I1Cr18Ni9Ti lining rubber lining tetrafluoroethylene.
3. Actuators (electric butterfly valve data)
Type: choose electronic quarter-turn actuators including QS series, 3810 series and DSR series.
