Electric flange ball valve is composed of electric actuator and ball valve. The actuator and the valve adopt direct connection mode, with delicate and beautiful appearance. Electric flange ball valve can be used with a variety of valve seat, room temperature type with PTFE seal, high temperature type can be used with para-polybenzene or metal hard seal, with low friction coefficient, small operating torque, leakage zui high up to zero leakage, etc., a variety of seat materials can be selected to adapt to a wider range. Electric flange ball valve according to the structure can be divided into two kinds of electric hard seal ball valve and electric soft seal ball valve. Electric flange ball valve with YTR series actuator can directly receive computer or industrial instrumentation output 4 ~ 20mADC or 1 ~ 5VDC control signals, according to the valve position feedback signal and the set value comparison deviation of the actuator drive motor for intelligent step adjustment (PID regulation), in order to achieve with the actuator supporting the accurate positioning of the opening of valves or other devices, and at the same time, the output of the position feedback signal of 4 ~ 20mADC, and the output of the position feedback signal. 20mADC position feedback signal.
The electric flange ball valve is particularly suitable for the medium is viscous, containing particles, fiber nature of the occasion, the electric flange ball valve is widely used in petroleum, chemical industry, metallurgy, light industry, papermaking, power station, refrigeration and other fields of work.
