BECK执行机构-阀门类

The Group 29 linear control valve actuator is a more modern variation of the time-proven Group 14.  Group 29 actuators incorporate a high-efficiency ball screw that allows for a wider range of thrust options in a smaller package.  The Group 29 also offers standard thrust sensing capabilities and it can be certified for service in both gas and dust hazardous location.  The Group 29 is well suited for linear control valve applications and can be offered with mounting hardware for almost and model valve requiring less than 27145 N and 19 mm stroke.  Important general actuator specifications include:

29系列直行程阀门执行机构相对于经典的14系列更现代化。29系列具有高效率的滚珠丝杆，可提供多种直行程控制选择方式。29系列也提供标准推力感应功能，可以在烟气危险工况环境下应用，适用于直行程阀门控制。结合贝克工厂生产的连接装置，几乎可以安装在所有小于27145 N和19 mm行程范围内的阀门。主要规范如下：
