American Standard gate valve plays the role of cutting off or connecting the medium in the pipeline, and can work well in the thermal power station, petroleum, chemical, and other working conditions pipeline with the temperature of -29℃～600℃, and the medium can be oil, water, steam, etc.
The structure length and characteristics of the American Standard gate valve are mainly as follows:
1. The American Standard gate valve meets the standard requirements of advanced process production at home and abroad; its sealing performance is good, and the shape is beautiful and generous. American Standard gate valves commonly use non-metallic seat materials.
2. The structure used in the gate valve is a wedge-type resilient gate structure, as well as medium and large-diameter set rolling bearings, with the advantages of low friction and easy opening and closing.
3. The gate and seat sealing surface is made of steel cobalt carbide overlay welding or iron-based alloy overlay welding, with high-temperature resistance, corrosion resistance, abrasion resistance, and long service life.
4. The American standard gate valve stems after tempering and surface nitriding treatment, with strong wear and abrasion resistance and corrosion resistance.
5. Can use a variety of piping flange standards and flange sealing surface types to meet the needs of various projects and user requirements.
