Description
2SA30/35 series actuators are used in process engineering for control or open {{{{and}}}} closing operation of valve in open-loop or closed-loop control equipment, where final control elements such as gate valve, isolating valve, control valve, etc. are actuated. The degree of protection can be up to IP68. The output torque range of 2SA30 series actuator is 10-4000Nm, the speed range is 5-160rpm, The output torque range of 2SA35 series actuator is 15-2800Nm, the speed range is 5-40rpm.
1. the series is the introduction of 90 new Siemens Siemens to design and obtain production permits;
2. advanced design, complete series can fully meet the needs of power stations and other automation control;
3. reasonable structure, versatility, can be adapted to the needs of a variety of supporting functions, the power control module to install 2SA30 LK, local and remote operation can be realized; with digital-based power for the module (three-phase MU, single-phase MD) is the mechanical and electrical integration of the electric actuator for the power plant DCS technology to provide more choices of space;
4. can provide more than two intermediate signal (ie, switch to the middle of signal);
5. with dust-proof, waterproof performance, the protection class is IP67, user requirements should also provide protection class IP68 electric actuator;
6. easy adjustment and control of high precision;
7. 2SA35 equipped with variable pole motor on, it can constitute a two-speed electric actuator can be used to 125MW ~ 600MW steam turbine bypass system, both the regulatory function, but also fast slow function.
