进口电动球阀

进口电动球阀只需要旋转90°即可全关全开。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。该阀适用于两位切断、调节的场合。主要分为两大类：电动软密封球阀和电动硬密封球阀，电动软密封球阀主要适用于温度低于250℃以内的介质。电动硬密封球阀主要适用于250℃以上的介质。德国汉克(HANK)电动球阀体积小、重量轻、推力大、功能强、伺服放大器内装、操作方便、可靠性高，球阀与执行器采用直连方式，内置伺服系统，无须另配伺服放大器，输入输出信号4-20mA及220VAC电源即可控制运转。具有连线简单、结构紧凑、动作稳定可靠等优点。电动球阀是一种重要的电动阀门类，在石油化工和长输管线等领域有广泛应用。它的关闭件是一个带孔的部分球体，球体随阀杆转动，实现阀门的开启或关闭。

1、流体阻力小、球阀是所有阀类中流体阻力最小的一种，即使是缩径球阀，其流体阻力也相当小。

2、止推轴承减小阀杆摩擦力矩，可使阀杆长期操作平衡灵活。

3、阀座密封性能好，采用聚四氟乙烯等材料制成的密封圈，结构易于密封，而且球阀的阀封能力随着介质压力的增设而增大。

4、阀杆密封可靠，由于阀杆只作旋转运动而不做升降运动，阀杆的填料密封不易破坏，且密封能力随着介质的压力增设而增大。

5、由于聚四氟乙烯等材料具有良好的自润滑性，与球体的摩擦损失小，帮球阀的使用寿命长。

6、下装式阀杆和阀杆头部凸阶防止阀杆喷出，如火灾造成阀杆密封破坏，凸阶与阀体间还可形成金属接触，确保阀杆密封。

GERMANY HANK VALVE LIMITED is founded on 1852 in Monchengladbach,which is located at one city in North Rhine in Germany, which is the west of Nordrhein-Westfalen. At the beginning of 1850s, as the rapid development of economic and the shortages of energy in Germany , the government had been in saving energy aspect. On this occasion, HANK Valve (Trouble Less Valve) was established.Hank valve is the world-famous transnational production enterprise,which produces high quality and advanced valve, measurement and control system, and which has its divisions and branches in dozens of countries in the global. The company products user involves the petroleum, the chemical industry, the electric power, the metallurgy, the drugs manufacture, food, the water treatment, the municipal administration to give draining water, the natural gas, the papermaking, the electronics industry, the building, the mechanical device necessary ect..

德国汉克（HANK）阀门的价值理念概括为：责任－远见－创新。我们因自身的责任感、远见及专注于创造前所未有的解决方案和理念，而成为全球领先的阀门制造商。

The conclusion of the valve concept in German Hank valve is resposibility,foresight,innovation. For ourselves resposibility, foresight and focusing on creating unprecendented solution and concept,our company has become the lead of valve manufacturer in the global.
