Thrust unit plus bracket can be customizeda
Main Features
1. The stroke of the linear-turn electric actuator is adjustable, which is convenient to connect with the valve.
2. All electrical components are reliable in quality and long in service life.
3. The wiring of the electrical parts of the actuator is rigorous and completely isolated from the transmission parts, which improves the reliability of the operation of the actuator
4. The actuator is connected to the valve with a flexible coil spring, which can avoid the influence of the valve stem and the output shaft being out of axis. The closing force of the valve can be preset to ensure the reliable closing of the valve and prevent leakage.
5. Simple structure, small size, light weight, easy installation and maintenance: all mechanical parts are made by CNC processing with exquisite workmanship. ' 6. The electric actuator is designed as an integrated structure. The position transmitter and the servo amplifier can be directly installed inside the actuator as two independent components, directly accepting the 4-20mA control signal, and outputting 4-20mA or 1-5DC valve Bit anti-debt signal, with self-diagnosis function, very convenient to use and adjust.
7. Functional modular structure design, through the combination of different options, realizes simple to complex control, and meets different application requirements
8. The transmission all adopts small backlash sealed gears, which have high efficiency, low noise, long service life, stability and reliability, and no need to refuel.
9. 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.
10. The driving motor on the 361 actuator is a high-speed synchronous motor made of high-performance rare earth magnetic materials, which runs smoothly. It has the advantages of small size, large torque, anti-stall, and high control precision.
11. Segmental adjustment can be set, that is, two actuators are controlled by a dual-time proportional signal output by a PID regulator (4-12mA corresponds to full open and full close of PSL1,
12-20mA corresponds to full open 1 full close of PSL2).
13. The valve position feedback element adopts a fully sealed high-precision multi-turn potentiometer, which has the characteristics of small size, high precision, small dead zone, and long service life.
