对夹球阀产品特点 对夹连接球阀具有结构紧凑、体积小、重量轻、 密封性能好、启闭灵活、安装方便等特点。主要适用于石油、化工、冶金、制药、食品等各类系统中。
而保温对夹连接球阀良好的保温保冷特性既能有效防止管路中粘稠介质凝固，又能降低管路中介质热量的损失。
本系列可装上相应的电动及气动装置,以实现遥控或自动控制。 Features The double-clip connected ball valve possess such features as compact structure, smaller volume, lighter ponderance, fine sealing performance,flexible on-off, convenient installation course, etc.
The heating double-clip connected ball valve enjoys favorable heat/cold preservation performances which not only effectively prevent the slabby medium in pipelines from solidifying but also reduce the heat loss of the medium in pipelines.
The double-clip connected ball valve series could also be applied with the mounted corresponding motor or air operated plant to implement remote control or automatic control. 技术规范Technical Specification | 结构形式 Structure form | 对夹式 Double-clip type | | 连接法兰 Connecting flange | ANSI B16.5、JB/T79 | | 驱动方式 Driving manner | 手动、电动、气动
