2SA3 series Siemens electric actuatorsDetailed product description：

Product Description

The 2SA3 series multi turn electric actuator is a driving device for various electric valves in process control systems, used to control the opening and closing of valves. It is suitable for gate valves, globe valves, diaphragm valves, and their derivative products can be used for valves with angular travel such as disc valves, ball valves, and dampers. It is an essential driving device for remote control, centralized control, and automatic control of valves, which can act accurately according to control instructions; The 2SA30 electric actuator is suitable for open-loop control systems, while the 2SA35 series electric actuator is suitable for closed-loop control systems. It can accurately adjust the medium pressure, temperature, and flow rate of the system according to control instructions, making it an essential driving device for achieving automatic control. The 2SA3 series multi turn electric actuator can be widely used in power plants, petrochemicals, metallurgy, public utilities, etc.

Has the following characteristics:
1. This series of products is based on the latest design from Siemens in the 1990s and has obtained a production license from Siemens;
2. Advanced design, complete series, and ability to fully meet the needs of automation control in power plants and other areas;
3. Reasonable structure, strong universality, and can meet the needs of various supporting functions. Installing the function control module LK on 2SA30 can achieve on-site and remote operation; When the LU intelligent power reversing module is installed on 2SA35, it becomes an intelligent electric actuator, providing a reliable intelligent device for the DCS technology transformation of power plants; The digital power control module (three-phase MU, single-phase MD) is an electromechanical integrated electric actuator, providing more options for DCS technology in power plants;
4. Can provide two or more intermediate signals (i.e. switch to intermediate signal);
5. It has dustproof and waterproof performance, with a protection level of IP67. Users can also provide an electric actuator with a protection level of IP68 upon request;
6. Easy adjustment and high control accuracy;
When equipped with a variable pole motor on 2SA35, a dual speed electric actuator can be formed, which can be used for the turbine bypass system of 125MW~600MW generator sets. It has both regulating function and fast/slow speed function
