进口不锈钢闸阀，Stainless steel gate valve，是指不锈钢闸阀：阀体、阀盖、闸板、闸杆使用不锈钢材料，阀座密封面为聚四氟乙烯、不锈钢+硬质合金或堆焊硬质合金，填料一般采用硬质合金、聚四氟乙烯、石棉石墨或柔性石墨。适用于温度 ≤200℃，适用于硝酸类、弱腐蚀性介质管路中。

美国威盾不锈钢闸阀主要产品：不锈钢闸阀，不锈钢法兰闸阀，不锈钢螺纹闸阀，304闸阀，316闸阀，奥氏体不锈钢闸阀。

Stainless steel gate valve, Stainless steel gate valve， It refers to stainless steel gate valves: the valve body, valve cover, gate plate, and gate rod are made of stainless steel material, the sealing surface of the valve seat is made of polytetrafluoroethylene, stainless steel+hard alloy or welded hard alloy, and the packing is generally made of hard alloy, polytetrafluoroethylene, asbestos graphite or flexible graphite. Suitable for temperatures ≤ 200 ℃, suitable for pipelines in nitric acid and weakly corrosive media.

三、进口不锈钢闸阀产品特点

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 suitable for pipelines where 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.
