进口电动截止阀

德国巴赫进口电动截止阀概述：

 进口电动截止阀是由截止阀和多回转电动执行器等电气控制元件组成的自控阀门系统，通常用在需要频繁开闭需要实现大规模集中控制的场合。工作时，接入220VAC或380V电源即可控制运转，也可加入控制模块，输入控制信号（4-20mADC或1-5VDC）进行调节控制，还可以加装手轮，在必要时进行人为手动控制。根据不同的工艺要求选配不同的电动执行器：如开关型、信号反馈型、防爆型、调节型等。

Imported electric globe valve

Overview of electric valve imported from Germany Bach:

Imports of electric valve is composed of valve control valve system and multi turn electric actuator and other electrical control components, usually used in the frequent large-scale centralized control occasions closed. When working, access 220VAC or 380V power to control operation, it can be added to the control module, the input control signal (4-20mADC or 1-5VDC) for regulation and control, can be equipped with a hand wheel, for manual control when necessary. According to the different requirements of the process of the selection of different types of electric actuators: such as switching, signal feedback, explosion-proof, adjustable type, etc..

 进口电动截止阀的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。阀杆的运动形式，有升降杆式（阀杆升降，手轮不升降），也有升降旋转杆式（手轮与阀杆一起旋转升降，螺母设在阀体上）。截止阀只适用于全开和全关，不允许作调节和节流。 

Imported electric valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. The movement of the stem form, there are lifting rod (stem lift, hand wheel is not up and down), but also with the rotation of the rotary rod (hand wheel and stem together with the rotation of the nut in the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.

进口电动截止阀的定义：

7、倒密封采用螺纹连接密封座或本体堆焊奥氏体不锈钢而成，密封可靠，更换填料可在不停机情况下进行，方便快捷，不影响系统运行。
8、配有DZW系列多回转式电动装置，具有壳体小，重量轻，功能全，并可与远程电脑配套使用，也可按用户要求选配电动装置。

The definition of imported electric valve:

1, material selection, in line with domestic and foreign standards, reasonable structure, beautiful appearance.

2, the valve flap and the valve seat sealing surface by the iron-based alloy surfacing or Slite (Slite) surfacing cobalt based alloy, wear resistance, high temperature resistance, corrosion resistance, good anti abrasion performance, long service life.

4, the stem through the quenching and tempering and surface nitriding treatment, good corrosion resistance and scratch resistance.

5, can be used with standard pipe flanges and flange sealing surface, to meet the needs of various projects and user requirements.

6, the valve body material is complete, packing, gasket can be based on actual conditions or user requirements reasonable matching, can be applied to all kinds of pressure, temperature and medium conditions.

7, the reverse seal with screw connection sealing seat or body welding austenitic stainless steel, reliable sealing, replacement of the packing can be in the case of non-stop, convenient, does not affect the operation of the system.

8, equipped with DZW series rotary electric device, has a small, light weight, full function, and can be matched with the remote computer, the user can also be equipped with electric device.
