Introduction to China stainless steel gate valve. A so-called stainless steel valve is a valve made primarily of stainless steel, which controls the flow of liquids (gas, liquids, liquids, or slurries) by opening, closing, or partially obstructing various passages.
It reacts with oxygen to form a hard, loyal, invisible, passive layer of chromium oxide film on the surface of the steel. In addition, additives such as nickel use to increase the general corrosion resistance required for more aggressive use or conditions.
Because of these components
It is famous for its corrosion and staining, low maintenance, relatively low cost, and resistance to known glare, and it is an ideal base material for commercial applications, especially for valve applications. Based on the properties of stainless steel, stainless steel ball valves have corrosion-proof, rust-proof, water-proof, and durability properties.
Therefore, it widely uses in many industries where corrosion resistance requires, such as chemical, petrochemical, oil, paper making, mining, electricity, gas, food, medicine, water supply, mechanical equipment, electronic, urban construction, and so on.
Nowadays, China stainless steel gate valves have become a necessary product in all types of cases. However, there are only a few valve manufacturers who reach international standards. So when people buy this valve, they must show the seller the certificates for production. In this way, people can avoid buying ineligible products.
Gate valves refer to valves that manufacture under regulations set by the American Petroleum Institute. These commonly use in the petroleum and industrial processing centers, which play an important role in stopping the flow. And it is true that their characteristic and core part call a wedge. To meet different specifications, gate valves actually design and manufactured in multiple sizes, ratings, and materials. However, the key elements of this mechanism are common. These are valve gate, valve body, valve bonnet, valve stem, and valve seat.
Classification and benefits of using gate valves
A gate valve is a device that helps control the flow of fluid through a pipe. The most fun in a wide range of pipes, these valves fit into the pipeline to start or stop the flow of water or any other type of fluid. These valves fix most pipes in homes and commercial centers. This article describes several important varieties and their different functions.
It is classified individually according to its wedges and its stems. These valves have fixed stems. Some stalks grow when the valve opens and such valves are known as rising stem valves. When the valve closes, its stem comes down. These types are not suitable if space limit.
The non-rising stem valve is another variation of the gate valve. When opening and closing the valve, the stem of this valve can neither ascend nor descend. It stays in the same position. These types of valves are in underground tunnels and in places where there is little space.
Gate valves separate on the basis of wedges
Valves with solid wedges have a simple but strong construction. So it can use for all kinds of liquids including strong liquids. Since it involves simple construction, it involves less complexity and maintenance. So it mostly uses in pipelines.
Valves with flexible wedges still have the ability to withstand a variety of weather conditions. Parallel side valves are common flexible wedge valves commonly used in many areas.
Another variation of the China stainless steel gate valve is the split wedge valve which is ideal for non-condensing gas and corrosive liquids.
Further, it can distinguish according to different bonnet styles. Screw-in bonnets commonly use for small applications because they work normally. Bolted bonnets use for large valves because they are suitable for complex applications.
Use of different materials: Different materials are used to make these valves. Some valves make of brass and some are iron. Used to make valves from stainless steel, cast iron, alloy steel, forged steel, and more.
