Company Profile

Products discription

HIC12 is a explosion-proof intelligent valve positioner. It adopts two-lines transmitting(power supply、4~20mA analog signals、double digital communication signals deliver on the two lines.).The work principle is different from the traditional electricity—gas valve positioner.HIC12 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.
