PSL and PSQ actuators are products launched by PS Automation GmbH, a German manufacturer of actuators. The PS series electronic actuator can be used for adjusting and controlling the opening and closing of valves and dampers in pipelines. The main features of this actuator and its accessories are as follows:
(1) Integrated structural design, the position transmitter and servo amplifier can be directly installed inside the actuator as two independent components, directly receiving 4-20mA control signals and outputting
4-20mA or 1-5VDC valve position feedback signal, with self diagnostic function, very convenient to use and calibrate.
(2) Functional modular structure design, through the combination of different optional functions, achieves control from simple to complex, meeting different application requirements.
(3) The structure is simple, compact in size, lightweight, easy to install and maintain, and all mechanical parts are made by CNC machining with exquisite craftsmanship.
(4) The transmission adopts small backlash sealed gears, which have the characteristics of high efficiency, low noise, long service life, stability and reliability, and no need for refueling.
(5) It has multiple operating speeds to meet the requirements of various control systems, ensuring fast response and stability of the system.
(6) The PSL series uses flexible coil spring connection to connect with the valve, which can avoid the influence of different shafts between the valve stem and output shaft on the valve. The valve closing force can be pre-set to ensure the reliability of the valve
Turn off to prevent leakage.
(7) The PSQ series has torque switch protection to prevent damage to the valve stem due to excessive torque generated by the valve.
(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 size, high torque, anti blocking, and high control accuracy.
(9) Segmented adjustment can be set, that is, the dual time proportional signal output by one regulator controls two actuators (4-12mA corresponds to fully open and fully closed PSL1, 12-20mA corresponds to
PSL2 fully open and fully closed.
(10) The valve position feedback component adopts a fully sealed high-precision multi turn potentiometer, which has the characteristics of small volume, high accuracy, small dead zone, and long service life.
(11) Adjustable stroke for easy connection with valves.
(12) All electrical components are made of world-renowned brand products, with reliable quality and long service life.
(13) The wiring of electrical components is rigorous and completely isolated from transmission components, which improves the reliability of the operation of the actuator.
