进口电动调节球阀产品概述：

德国《LOCKE》洛克--进口电动调节球阀适用于两位切断、调节的场合。球阀与执行机构的连接采用直连方式，电动执行机构内置伺服系统，无须另配伺服放大器，输入4-20mA信号及220VAC电源即可控制运转。电动调节球阀具有连线简单，结构紧凑、尺寸小、重量轻、阻力小、动作稳定可靠等优点。电动调节球阀通常用于密封要求严格的场合，除控制气体、液体、蒸汽介质外，还适宜控制污水和含有纤维性杂质的介质，广泛用于石油、化工、冶金、轻工、造纸、电站、制冷等工作领域。电动调节球阀是一种重要的阀类，在石油化工、长输管线等领域有广泛应用。球阀的关闭件是一个带孔的球体（或部分球），球体随阀杆转动，实现阀门的开启或关闭。电动调节球阀旋转90°即可全关全开，与相同规格的闸阀、截止阀比较、球阀体积小、重量轻，便于管道安装。

进口电动调节球阀产品特点：

1．结构简单、体积小、重量轻。

2．流体阻力小，全通径的球阀基本没有流阻。

3．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。

4．由于球阀在启闭过程中有擦拭性，所以可用于带悬浮固体颗粒的介质中。

5．操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制

6．紧密可靠。它有两个密封面，而且目前球阀的密封面材料广泛使用各种塑料，密封性好，能实现完全密封。在真空系统中也已广泛使用。

7．在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。

8．适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。

Introduction of imported electric control ball valve products:

German "Locke" - imported electric control ball valve is suitable for two position cut-off and adjustment. The ball valve is directly connected with the actuator. The electric actuator has a built-in servo system. It does not need to be equipped with another servo amplifier. The operation can be controlled by inputting 4-20mA signal and 220VAC power supply. The electric control ball valve has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action, etc. Electric control ball valve is usually used in the occasions with strict sealing requirements. In addition to controlling gas, liquid and steam medium, it is also suitable for controlling sewage and medium containing fibrous impurities. It is widely used in petroleum, chemical industry, metallurgy, light industry, papermaking, power station, refrigeration and other work fields. Electric control ball valve is an important kind of valve, which is widely used in petrochemical industry, long-distance pipeline and other fields. The closing part of the ball valve is a ball (or part of the ball) with a hole. The ball rotates with the stem to open or close the valve. Compared with gate valve and stop valve of the same specification, the ball valve is small in volume and light in weight, which is convenient for pipeline installation.

Features of imported electric control ball valve:

1. Simple structure, small volume and light weight.

2. The fluid resistance is small, and the ball valve with full diameter basically has no flow resistance.

3. Easy maintenance, simple structure of ball valve, movable sealing ring, easy disassembly and replacement.

4. The ball valve can be used in the medium with suspended solid particles due to its wiping property in the process of opening and closing.

5. Convenient operation, fast opening and closing, from full open to full close as long as 90 ° rotation, convenient for remote control

6. Tight and reliable. It has two sealing surfaces. At present, all kinds of plastics are widely used in the sealing surface material of ball valve, which has good sealing performance and can realize complete sealing. It has been widely used in vacuum system.

7. When the valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface.

8. Wide range of application, diameter from small to several millimeters, to several meters, from high vacuum to high pressure can be applied.
