[Electric] using steel ball principle:
90 ° rotation of electric steel ball valve can be realized fully open, fully closed, for a variety of pipeline, do open and close by. Compared with the same specifications gate and globe valves, valve passage and connected to a diameter equal to the diameter and the medium is almost no loss of flow.
【电动铸钢球阀】使用原理:
电动铸钢球阀旋转90°即可实现阀门的全开、全关,适用于各种管路上,做启闭用。与相同规格的闸阀和截止阀比较,阀体通道和连接管径相等并成一直径,介质几乎可以毫无损失的流过。
【电动铸钢球阀】特点:
直通的流道、流体阻力小;
启闭迅速(90°开关);
结构紧凑、体积小、重量轻;
密封可靠,密封面与球面常在闭合状态,不易被介质冲蚀;
直连方式,电动执行机构内置伺服系统,无须另配伺服放大器,输入输出信号4-20mA及AC380V电源即可控制运转;
操作简单,开闭迅速,从全开到全关只要旋转90°,便于远距离的控制;
维修方便,球阀结构简单,密封圈一般都是活动的,拆卸更换都比较方便。
[Electric] steel ball valve features:http://www.shhuguan.com/798.html
Through the flow channel, the fluid resistance is small;
Open and close rapidly (90 ° switch);
Compact structure, small size, light weight;
Reliable sealing, often spherical surface and seal in the closed state, can not easily be eroded media;
Direct Connect mode, the built-electric actuator servo system need to reprovision the servo amplifier input and output signals 4-20mA and AC380V power to control operation;
Simple, open and close rapidly, from fully open to fully closed as long as the rotation 90 °, to facilitate remote control;
Easy maintenance, simple ball valve, seals are generally activities, removal replacement is more convenient.
