电液推杆蝶阀，普遍适用于建材、玻璃、矿山、电力、轻工、造纸等行业的通风、环保工程等管道系统中快速启闭,调节流量大小和切断。
This valve is widely used in the pipe system such as venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. It can change the flow and cut off gas medium in the pipe by the different control signal.
结构特点：
Structure characteristic:
电液推杆蝶阀，采用优质碳素钢焊接。具有设计新颖、重量轻、结构紧凑、流阻损失小、操作灵活、指示方位明确、维护方便、使用寿命长等优点。可水平安装或垂直安装。配用电液推杆及有关配件，能实现现场和远距离控制，限位装置能有效的控制阀门的开度，推力和拉力及工作速度可按需要无级调整。
The valve is welded in fine carbon steel, having the features of light weight, compact structure, endurance, little in the lost of flow resistance, definite direction, easy to maintenance and long life. It can be installed in horizontal or vertical. The valve is used with electric-hydraulic draw stem and other accessory to form a complete set to realize local and remote control. The limit device can control the open angle of valve effectively. Thrust, pull and working velocity can be adjusted steplessly by requirement.
