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.
