Siemens electric actuator product design is advanced, the series is complete, can fully meet the automation control needs of power plants, petrochemical, metallurgy and mining industries. Siemens electric actuators are suitable for controlling or adjusting linear valves of various types of regulating valves in open-loop or closed-loop control systems; 2SB series electric actuators are constructed on the basis of 2SA series electric actuators. , It is a straight stroke electric actuator.
Siemens electric actuators are used for Siemens two-way valves and three-way valve. Selectable with spring return function, linear or proportional flow characteristics, valve position feedback, stroke check, LED status display, forced control function, manual adjustment and position indication, directly mounted on the valve, no adjustment required, can be passed Additional auxiliary switches, stem heating elements and mechanical stroke inverters are added to enhance functionality. Siemens electric actuator installation requirements are:
1. The installation of the electrical part of the regulating valve shall be carried out in accordance with the relevant electrical equipment construction requirements. If explosion-proof products are to be installed in accordance with the requirements of the “Electrical Equipment Installation Criteria for Explosion Hazardous Locationsâ€.
2. The pipeline for installing the regulating valve should not be too high from the ground or the floor. When the pipeline height is greater than 2m, the platform should be set as much as possible to facilitate the operation of the handwheel and facilitate maintenance.
3, Siemens electric actuators should generally be installed vertically, under special circumstances can be tilted, such as the tilt angle is very large or the valve itself is too heavy, the valve should increase support for protection.
4, Siemens control valve is a field instrument, the requirements of the ambient temperature should be in the range of -25 ~ 60 °C, relative humidity ≤ 95%. If it is a control valve installed in open air or high temperature applications, waterproof and cooling measures should be taken.
5, Siemens electric actuators in the event of failure or maintenance of the production process can continue to proceed, the regulator valve should be added to the bypass pipe, but also should pay special attention to the installation position of the regulating valve is consistent with the process requirements.
6. Before Siemens electric actuator control valve is installed, the pipeline shall be cleaned to remove dirt and welding slag. After installation, the valve should be cleaned again to ensure that no impurities remain in the valve body. After using the handwheel mechanism, it should be restored to its original neutral position.
