一、进口不锈钢美标截止阀概述

进口不锈钢美标截止阀，Stainless steel American Standard API globe valve，也叫美标磅级截止阀，美标法兰截止阀，美标不锈钢截止阀，150Lb截止阀，300LB截止阀，是指阀体采用不锈钢304或者316材质，设计制造符合美国国家标准ANS1B16.34,美国BS1873的截止阀。

阀体外形为桶形或流线形造型美观。流通形状为直通式。流体阻力小。

Stainless steel American Standard API globe valve, also known as American pound globe valve, American flange globe valve, American stainless steel globe valve, 150Lb globe valve, 300LB globe valve, refers to a globe valve with a valve body made of stainless steel 304 or 316 material, designed and manufactured in accordance with American national standard ANS1B16.34 and American BS1873.

The valve body has a barrel shaped or streamlined shape that is aesthetically pleasing. The flow shape is straight through. Low fluid resistance.

三、进口不锈钢美标截止阀优点
1、流体阻力小，其阻力系数与同长度的管段相等。 　　
2、结构简单、体积小、重量轻。 　　
3、紧密可靠，目前闸阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。 　　
4、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。 　　
5、维修方便，闸阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。 　　
6、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。 　　
7、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， 球旋转90度时，在进出口处应全部呈现球面，从而截断流动。

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length. 

2. Simple structure, small size, and light weight. 

3. Tight and reliable, plastic is widely used as the sealing surface material for gate valves with good sealing performance, and it has also been widely used in vacuum systems. 

4. Convenient to operate, quick to open and close, with only a 90 ° rotation from full open to full close, facilitating remote control. 

5. Easy to maintain, the gate valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement more convenient. 

6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface. 

7. Widely applicable, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should all appear spherical at the inlet and outlet to cut off flow.
