Smart valve positioner

HIC*1 is a explosion-proof intelligent valve positioner. It adopts two-lines transmitting(power supply4~*0mA analog signalsdouble digital communication signals deliver on the two lines. ). The work principle is different from the traditional electricity_gas valve positioner. HIC*2 explosion-proof intelligent valve positioner and pneumatic actuator make up of a feedback controlling loop, where the position feedback signal of control valve is regarded as controlled variable compared with the fixed signal value in the microprocessor. The warp of these two signals emits the pulse of different length by the output of the main control board that controls I/P conversion unit pressure output, and drives the control valve to act
