Product description: 
 The PSL, SQ executing agency is the executive body of the German PS Automation GmbH manufacturers to launch products. 
 PS Series electronic actuator can be used for pipeline valves and throttle regulation and control on and off, its main features are as follows: 
 (1) the integration of structural design, position transmitter, and servo amplifiers as two separate components can be loaded directly within the executing agency, to accept 4-20mA control signal, output 4-20mA or 1-5VDC valve position feedback signal , with a self-diagnostic function, use and adjustment is very convenient. 
 (2) The structural design of the functional modules, through a combination of different optional features to meet different application requirements from simple to complex control. 
 (3) simple structure, small size, light weight, easy installation and maintenance, mechanical parts used in all production CNC machining and workmanship. 
 (4) transmission is used in all small backlash gear seal, with high efficiency, low noise, long life, stable and reliable without having to add oil characteristics. 
 (5) with a variety of speed, which can meet the requirements of the various control systems to ensure that the system's rapid response and stability. 
 (6) the PSL series connection with the valve, the flexible coil spring connection, you can avoid the impact to the valve in the stem and the output shaft axis, you can preset the valve shut off power to ensure reliable valve shutdown to prevent leakage. 
 (7) PSQ series torque switch protection, to prevent too large due to the valve torque damage to the stem. 
 (8) drive motor with high performance rare earth magnetic materials produced by high-speed synchronous motor, smooth operation. Small size, high torque, anti-stall control of high precision. 
 (9) can be set to segment adjusted by a proportion of dual-time regulator output signal to control the two implementing agencies (4-12mA corresponds to the PSL1 the fully open fully closed, 12-20mA corresponds to PSL2 fully open to fully closed). 
 (10) sealed high-precision multi-turn potentiometer valve position feedback elements with small size, high precision, small dead zone, long life characteristics. 
 (11) adjustable stroke, easy connection with the valve. 
 (12) All electrical components are world famous brand products, reliable quality and long service life. 
 Electrical components wiring (13) is rigorous and complete isolation and transmission parts to improve the executive body to run reliable. 
 Product Structure: 
 Executive body of the PS series of electrical components wiring rigorous and complete isolation and transmission components, to improve the operating reliability of the implementing agencies, transmission parts using CNC machining of small backlash sealed gear drive with high efficiency, low noise, long life, stable and reliable, not the process environment, such as fluctuations in the medium inlet force caused by the resonance characteristics of the implementing agencies. 
 1.PSL straight actuator 
 PSL linear actuators is isolated electrical control and gear drive parts. As intermediate components to connect two isolated parts of the motor, the motor output torque control requirements, a multi-polar spur gear pass to the trapezoidal screw, the screw rod threaded transform torque thrust. This rod threaded self-locking, and the straight-line travel by pass valve adapter to the stem. The executive body of the shaft with a stop to prevent rotation reseller radial shaft locking device can be used as a position indicator. 
 Locking device with a connecting rod, connecting rod synchronized with the output shaft running through the circuit board connected to the rod will convert the output shaft displacement into an electrical signal as a signal and valve position feedback output to the servo amplifier while implementing institutions The trip may also be the two main limit switch switch panel to limit, by two mechanical limit of block to adjust the limit position. 
 2.PSQ angle actuator 
 The PSQ rotary actuators mainly by isolated electrical control and gear drive parts, motor as connecting two isolated parts of the intermediate components. Through the main gear transmission, the motor torque to the planetary gear, main gear drive planetary gear driven hollow gear. Hollow gear, three less than two gear teeth, by the hollow gear of planetary gear drives, planetary gears turn a week so you can turn the three teeth, outside of the planetary gears are always meshing of a worm gear is not separate, run-time, this design allows the motor unexpected failure or valve torque increase can be directly through the hand wheel for manual control. 
 Institutions limit the file only two threads executing agency, there are two limit switches to the electric limit, the travel range of each turn can be the location of the limit switch to control the valve opening is indicated by a raised display unique torque switch is adjustable from 50% -100% of the maximum torque, torque protection to prevent the damage of the stem when the valve is stuck.
