高性能密封 蝶阀

HIGH PERFORMANCE SEALED BUTTERFLY VALVE

高性能密闭蝶阀,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。 对管道中气体介质按不同控制信号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:

高性能密闭蝶阀 具有重量轻、结构紧凑、耐磨损、流阻损失小、工作压力高、密封压差大、操作灵活、指示方位明确、维护方便、使用寿命长等优点。可任意角度安装,特别适用于调节切断和要求快速自保的场合。配用 DKJ 、 ZKJ 、伯纳德等电动执行器及有关配件,可实现手动、自动无干扰切换,微机程控、自动控制或中央集中控制,是实现自动化控制操作、调节流量的理想设备。

The valve has the features of lightweight, compact structure, endurance, little in the lost of flow resistance, high working pressure, flexible operation, definite direction, easy to maintenance and long life. It can be installed at any angle. It is suitable in the condition of adjusting, cutting off and self-protecting quickly. The valve is used with DKJ, ZKJ, Bernard electric actuator and other accessory to form a complete set to realize manual and automatic exchange without interference, micro-computer long-range control, automatic control or center concentrating control. It is the ideal equipment of realizing operation of automatic control and adjusting flow.
