進口電動球閥

進口電動球閥只需要旋轉90°即可全關全開。閥體通道和連接管徑相等并成一直徑，介質幾乎可以毫無損失的流過。該閥適用于兩位切斷、調節的場合。主要分為兩大類：電動軟密封球閥和電動硬密封球閥，電動軟密封球閥主要適用于溫度低于250℃以內的介質。電動硬密封球閥主要適用于250℃以上的介質。德國漢克(HANK)電動球閥體積小、重量輕、推力大、功能強、伺服放大器內裝、操作方便、可靠性高，球閥與執行器采用直連方式，內置伺服系統，無須另配伺服放大器，輸入輸出信號4-20mA及220VAC電源即可控制運轉。具有連線簡單、結構緊湊、動作穩定可靠等優點。電動球閥是一種重要的電動閥門類，在石油化工和長輸管線等領域有廣泛應用。它的關閉件是一個帶孔的部分球體，球體隨閥桿轉動，實現閥門的開啟或關閉。

1、流體阻力小、球閥是所有閥類中流體阻力最小的一種，即使是縮徑球閥，其流體阻力也相當小。

2、止推軸承減小閥桿摩擦力矩，可使閥桿長期操作平衡靈活。

3、閥座密封性能好，采用聚四氟乙烯等材料制成的密封圈，結構易于密封，而且球閥的閥封能力隨著介質壓力的增設而增大。

4、閥桿密封可靠，由于閥桿只作旋轉運動而不做升降運動，閥桿的填料密封不易破壞，且密封能力隨著介質的壓力增設而增大。

5、由于聚四氟乙烯等材料具有良好的自潤滑性，與球體的摩擦損失小，幫球閥的使用壽命長。

6、下裝式閥桿和閥桿頭部凸階防止閥桿噴出，如火災造成閥桿密封破壞，凸階與閥體間還可形成金屬接觸，確保閥桿密封。

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..

德國漢克（HANK）閥門的價值理念概括為：責任－遠見－創新。我們因自身的責任感、遠見及專注于創造前所未有的解決方案和理念，而成為全球領先的閥門制造商。

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.
