Electric - driven control valve is consisted of bellows control part, shell, valve leader, spring, loop and sealing part. It is not developed and fabricated successfully in China because the bellows as a core part of it can not lie processed. Based on many year experience in producing sensitive elements, we successfully developed the control valve and could meet the performance requirements.%电动控制阀由波纹管控制件、壳体件、活门杆件、弹簧、密封件线圈等零部件组成,因对控制阀的核心关键件波纹管组件研制生产的困难,目前国内还没有别的厂家自主研制成功.本公司根据多年的敏感元件生产经验,对控制阀进行了国产化研制.经过批产考验,其研制的产品性能满足要求,形成了自主设计的产品.
