Flowchart of the production process for American standard gate valves

Many customers are confused; they simply ask why ANSI standard gate valves are so much more expensive than those of the national standard Next, I will give you a brief introduction to the production process of American standard gate valves. First: rough selection of the raw materials. http://www.xyzhf.com/uploadfile/2015/0706/20150706031743210.jpg For each batch of blanks that arrives, we conduct a selection process; any defective castings are sent back immediately to avoid unnecessary waste in processing. Second, rough machining of the raw material: http://www.xyzhf.com/uploadfile/2015/0706/20150706032104439.jpg Rough machining includes working on the flanges, the middle section, and the supports. Third, the surface and inner diameter of the semi-finished product are treated with shot blasting: http://www.xyzhf.com/uploadfile/2015/0706/20150706032250336.jpg This shows the result after shot blasting – there are no sand particles on the valve body’s surface, the surface is smooth, the overall color is uniform, and there are no signs of grinding. Four, further deep processing. http://www.xyzhf.com/uploadfile/2015/0706/20150706032507363.jpg For the processing of the waterline section, following this procedure helps to prevent the waterline from being damaged, thus protecting its pattern from damage. Five, final surface treatment: http://www.xyzhf.com/uploadfile/2015/0706/20150706032746558.jpg. Six, export packaging: http://www.xyzhf.com/uploadfile/2015/0706/20150706032839703.jpg. Seven, shipment. The above constitutes the entire production process for American-standard valves.
The above should help everyone gain a better understanding of the process related to outlet valves; I hope it is useful to all
A very intuitive presentation; thanks for the help! Same question: What is the production process for national standard valves, and what are the differences compared to American standard valves?
OP, looking forward to learning about the various differences between national standard valves and American standard valves.
What’s the difference? I think the US standard is more expensive due to the wall thickness.
It will take a few days; I have some minor matters to deal with these days, sorry
There are also national standard products with wall thicknesses that meet the requirements, but their price is lower than that of American standard products.
Looking forward to learning about the differences in the poster’s subsequent updates*
