BECK 22 系列

The Beck Group 22 product line provides rotary actuation for high torque applications typical of large power boiler ID and FD fan damper applications.  Like the Group 11 family, the Group 22 line also provides precise, continuous modulation that remains precise and consistent over time without required maintenance.  They also can modulate continuously or as much as the control loop requires without overheating. Beck Group 22 actuators eliminate the control, performance, reliability and maintenance problems inherent of other actuators used on high torque, critical applications.  The Group 22 reliability and performance makes it a standard throughout North American on large coal-fired boilers.

贝克22系列执行机构为大扭矩应用提供调节型控制，主要用于高功率锅炉的ID和FD风门挡板。同11系列执行机构一样，22系列的调节控制同样精确，连贯，使用寿命长，而且免维护；可以遵照控制环路的要求进行持续的精确调节而不会过热。22系列消除了一般执行机构在大扭矩关键控制时，在精确度，连续性，可靠性及维护方面的各种问题，其可靠性和优越的性能使之成为北美大型火电厂的行业标准。

The Group 22 line offers torque ranges from 4000 Nm (3000 lb-ft) to 10,850 Nm (8000 lb-ft) making it the perfect choice for any large fan damper.  The features, performance and reliability of Beck Group 22 actuators are unmatched by other actuators in this size range.  Important specifications for the Group 22 are as follows:
