Firt, Product Overview
YT 1000 series electric positioner and pneumatic control valve, constitute  a closed loop control circuit. To convert the dc current signal control system  is given to drive letter of gas valve control valve action. At the same time  according to the feedback regulator of the opening to make the valve  position can correct positioning according to the system output control  signals. The electrical locator is available In the type single acting (spring  return type) and double-acting pneumatic actuators.
