■ product structure
PSQ rotary actuators is mainly isolated from each other and the electrical control gear components, electrical isolation as part of the middle connecting the two parts.Torque transmitted through the main gear to the planetary gear, main gear-driven hollow gear planetary gear drive. Hollow gear teeth, three less than second gear, it can be driven by the planetary gears, planetary gears rotate one revolution of three hollow gear teeth meshing planetary gear has a worm gear outside, run-time is not separated from the motor of this design the failure or unexpected increase in torque when the valve directly through the hand wheel for manual control.
There are two threads executing agencies only limit file organization, there are two limit switches to achieve the power limit for each turn of the travel range limit switch position can be controlled, the valve opening direction by a raised display The unique adjustable torque switch from 50% - of the maximum torque, torque to achieve protection against being stuck valve stem damage caused by

Inligent controller PSAP4
PSAP4 support for the PS inligent electric actuator proportional servo circuit, the use of SMT technology, small size and high reliability. This circuit will control the electric actuator 4-20mA current signal, and the implementing agencies to compare the current position signal, and the situation according to the deviation, the control actuator on or off action, the executive body position and balance of the input signal.
PSAP4 implementing agencies in achieving the 4-20mA signal with the input action is also provided to the system and the work of a group of power supply, isolated from the input signal 4-20mA position signal.
PSAP4 can easily adjust the starting position of the implementing agencies and travel; can easily achieve positive / counter switch; set when the input signal fails, the actuator is set to fully open, fully closed or on hold.
■ Work
Position signal conversion circuit implementing agencies will be reflected in the 1000 European three-position slide resistance change of the signal into 4-20mA. Control input signal at the same time and location compared to the error amplifier to compare the results of the control solid state switch-off, the implementing agencies to achieve control on or off. According to the control for adjustment of sensitivity, can change the tracking accuracy and the elimination of the inertia that may arise due to mechanical oscillation.
