三、进口不锈钢法兰闸阀产品特点

1、不锈钢闸阀采用奥氏体不锈钢，对氧化性酸介质拥有良好的耐蚀性。

2、不锈钢闸阀介质流经不锈钢闸阀时不改变其流动方向，流体阻力小。

3、不锈钢闸阀闸板运动方向与介质流动方向相垂直，启闭力矩小，开闭较省力。

4、不锈钢闸阀介质流动方向不受限制，不扰流、不降低压力，介质可从闸阀两侧任意方向流过、均能达到使用的目的，最适用于介质流动方向可能改变的管路中。

5、不锈钢闸阀闸板垂直置于阀体内，结构长度较短。

6、不锈钢闸阀密封性能好。全开时密封面受冲蚀较小。

1. Stainless steel gate valves are made of austenitic stainless steel, which has good corrosion resistance to oxidizing acid media.

2. When the medium of stainless steel gate valve flows through the stainless steel gate valve, its flow direction does not change, and the fluid resistance is small.

3. The movement direction of the stainless steel gate valve is perpendicular to the flow direction of the medium, with a small opening and closing torque, making it easier to open and close.

4. The flow direction of the medium in stainless steel gate valves is not restricted, does not disturb flow, does not reduce pressure, and the medium can flow in any direction from both sides of the gate valve, achieving the purpose of use. It is most sui for pipelines the flow direction of the medium may change.

5. The stainless steel gate valve is vertically placed inside the valve body, with a shorter structural length.

6. The stainless steel gate valve has good sealing performance. When fully open, the sealing surface is less susceptible to erosion.
