4. Action Principle
YT-1000L TYPE
When the set-point signal input, the torque motor(1)generate a electromagnetic field, the baffle(2)received and leave away from the nozzle(3). The air which in the pilot valve(4)will be elimination, and push the valve core(8), Air input to the actuator(11) through the base(7). With pressure increase, the push rod(12)go down, the feedback stem(13)pull the spring(16). Until the force between the spring(16)and the torque motor(1)keep balance, the baffle(2)go back. Then the valve core(8)gag the base(7)again, the positioner keep stable.
