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.
