There are two types of butterfly-valve: switch and intelligent. Matching with the DSR actuator butterfly valve, the input control signals ( 4 ~ 20 madc or 1 ~ 5 VDC) And single-phase power supply, so the operation of the electric butterfly valve can be controlled. Electric butterfly valve has the features of strong, small size, reliable performance, simple, large flow capacity. It is light weight, easy to use, especially suitable for viscous medium including the performance of the particles and fibers. 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 such as industrial automatic control system. Here are some electric butterfly valve performance parameters are as follows: 1. Electric butterfly Industrial Valves, Body data) Nominal size: 50 - 1200mm。 Nominal pressure: PN1. 0 and 1. 6 mpa and 2. 5. Connection: JB/T78 - 59 - 59 jb79 clamping flange connection.
