Summary
PS series electronic electric actuators, namely PSL and PSQ actuators, are products launched by German manufacturers of PS Automation GmbH actuators. PS series electronic actuators can be used to regulate and control the opening and closing of pipeline valves and dampers.

main features
(1) Integrative structure design, position transmitter and servo amplifier as two independent components can be directly loaded into the actuator, directly accept 4-20mA control signal, output 4-20mA or 1-5VDC valve position feedback signal, with self-diagnosis function, easy to use and adjust.
(2) Functional module structure design, through the combination of different optional functions, realizes from simple to complex control, and meets different application requirements.
(3) It is simple in structure, compact in size, light in weight, easy to install and maintain, and all mechanical parts are processed and manufactured by CNC with exquisite workmanship.
(4) All gears are sealed with small backlash, which has the characteristics of high efficiency, low noise, long service life, stability and reliability, and no need to refuel.
(5) It has a variety of operating speeds, which can meet the requirements of various control systems to ensure the rapid response and stability of the system.
(6) The PSL series is connected with the valve by flexible disc spring, which can avoid the influence of the different axes between the stem and the output shaft on the valve, and can preset the closing force of the valve to ensure the reliable closing of the valve and prevent leakage.
(7) PSQ series has torque switch protection to prevent valve stem damage due to excessive torque.
(8) 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.
(9) Segmental regulation can be set, i.e. two actuators are controlled by a dual-time proportional signal output from one regulator (4-12mA corresponds to full-open and full-close of PSL1 and 12-20mA corresponds to full-open and full-close of PSL2).
(10) 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.
(11) The stroke can be adjusted to facilitate the connection with the valve.
(12) All electrical components adopt world famous brand products with reliable quality and long service life.
(13) The wiring of electrical components is rigorous and completely isolated from the transmission components, which improves the reliability of the operation of the actuator.

Product Structure of PS Series Electronic Electric Actuator
PS series actuators have strict wiring and complete isolation from the transmission components, which improves the reliability of the operation of the actuator. The transmission components are driven by small clearance sealed gears processed by CNC, which have high efficiency, low noise, long service life, stability and reliability, and will not be stubborn due to the fluctuation of the process environment, such as the entrance force of the medium. Resonance of traveling mechanism.
PSL series straight-stroke electric actuator *** has a large stroke of 100 mm and a large thrust of 25 KN. It is suitable for valve switch and adjustment control in linear operation.
