3. Simple structure, compact size, light weight, easy to install and maintain, all mechanical parts are processed by CNC, exquisite technology.
4. All gears are sealed with small backlash, which has high efficiency, low noise, long service life, stability and reliability, no refueling, and various operating speeds. It can meet the requirements of various control systems to ensure the rapid response and stability of the system.
5. PSQ series has torque switch protection to prevent valve stem damage due to excessive torque.
6. The driving motor is a high-speed synchronous motor made of high-performance rare earth magnetic materials, which runs smoothly. It has the characteristics of small volume, large moment, anti-blocking and high control precision.
7. Segmental regulation can be set, i.e. two actuators can be controlled by a dual-time proportional signal output from one regulator (4-12mA corresponds to full-open or full-closed PSL1, 12-20mA corresponds to full-open or full-closed PSL2).
8. The valve position feedback element adopts fully sealed high precision multi-loop potentiometer, which has the characteristics of small volume, high precision, small dead zone and long service life. All electrical components adopt world famous brand products with reliable quality. The wiring of electrical components is rigorous and completely separated from the transmission components, which improves the reliability of the operation of the actuator.
product mix
The PSQ angular stroke actuator is mainly composed of the separated electrical control part and the gear transmission part. The motor is used as the intermediate part to connect the two separated parts. The motor torque is transmitted to the planetary gear through the main gear, which drives the planetary gear to drive the hollow gear. Hollow gears have three fewer teeth than secondary gears, so they can be driven by planetary gears. The planetary gears rotate three teeth in a circle. The outer part of the planetary gears always engages a worm gear, and the operation is not separated. This design enables the motor to operate directly through the handwheel when the fault or the valve torque increases unexpectedly. Dynamic control.
The actuator has two threaded stop mechanism limits and two limit switches to realize the electric limit. The range of each turn can be controlled by the position of the limit switch. The opening of the valve is indicated by a protruding display. The unique torque switch can adjust the maximum torque from 50% to 100%, so as to realize the torque protection to prevent it. Stem damage when valve is stuck.

PSQ Type Electric Actuator Intelligent Controller PSAP4
PSAP4 is an intelligent proportional servo circuit for PS electric actuator. It adopts SMT technology and has the characteristics of small size and high reliability. The circuit will control the 4-20mA current signal of the electric actuator, and compare it with the current position signal of the actuator. According to the deviation, it will control the opening or closing action of the actuator to balance the position of the actuator with the input signal.
PSAP4 provides a set of 4-20mA position signals which are isolated from the working power supply and input signal while the actuator acts with the input 4-20mA signal.
PSAP4 can easily adjust the starting position and travel of the actuator; can easily achieve positive/negative switching; set the actuator to be fully open, fully closed or maintained when the input signal fails.
Principle of PSQ Electric Actuator
The position signal conversion circuit changes the resistance signal of 1000 Euro three-line sliding line reflecting the position of the actuator to 4-20 mA. The control input is compared with the position signal sent to the bias amplifier at the same time. The comparison results control the on-off of the solid-state switch and realize the on-off control of the actuator. By adjusting the sensitivity according to the control requirements, the tracking accuracy can be changed and the possible oscillation caused by mechanical inertia can be eliminated.
