Electric actuators can be used for valves and dampers pipeline regulation and control on and off, its main features are as follows:
1, integrated structural design, position transmitter and servo amplifier as two separate components can be loaded directly into the internal implementing agency, directly accept 4-20mA control signal, output 4-20mA or 1-5VDC valve position feedback signal, with self-diagnostic function, very convenient to use and adjust.
2, functional modular design, by combining different optional features, from simple to complex control, to meet different application requirements.
3, simple structure, small size, light weight, ease of installation and maintenance, mechanical parts used in all CNC machining, technical skills.
4, drive in all small sealed gear backlash, high efficiency, low noise, long life, stable and reliable, no plus oil characteristics.
5, with a variety of operating speed, can meet the requirements of the various control systems to ensure that the system of rapid response and stability.
6, connecting the valve connection with flexible coil spring, to avoid the stem shaft and the output shaft different impact caused valves, shut off valves can be preset to ensure a reliable power shut off valve to prevent leakage.
7, drive motor with high performance rare earth magnetic material, high-speed synchronous motor, smooth operation. With small size, torque, anti-stall, control accuracy.
8, can be set up sub-regulation, which consists of a two-time controller output signal to control two proportional actuator (4-12mA PSL1 corresponding to fully open fully closed, 12-20mA PSL2 correspond fully open fully closed).
9, the valve position feedback element is fully sealed precision multi-turn potentiometer, with small size, high precision, small dead zone, long life and other characteristics.
10, adjustable stroke, easy to connect with the valve.
