China Gate Valve

A gate valve is a type of valve that uses a gate or wedge-shaped disc to stop or start the flow of a fluid. The gate is attached to a stem that is operated by a handle or a wheel, and it can be raised or lowered to open or close the valve. When the gate is fully raised, it allows the fluid to flow freely through the valve. When the gate is fully lowered, it blocks the flow of the fluid.

Gate valves are widely used in a variety of applications, including oil and gas, chemical processing, water treatment, and power generation. They are available in a range of sizes and materials to suit different applications and fluid types.

In China, gate valves are commonly used in industrial piping systems and are designed to meet Chinese national and industry standards. They are known for their reliability, durability, and ease of use, and they are often used in applications where a tight seal is required to prevent leaks. Like JIS flanged ball valves, gate valves are typically connected to the rest of the piping system using flanges, which are fastened together with bolts or other fasteners.

The valve body of the gate valve can be made of metal. Such as: forged steel gate valve, stainless steel gate valve, alloy gate valve, bronze gate valve, cast steel gate valve, carbon steel gate valve, etc. Among them, forged steel gate valves are widely used, especially as a cut-off device when the size is greater than 50mm. The main body can also be made of non-metallic materials. For example, ceramic gate valves have good wear resistance and hardness. Some other gate valves are made of special materials, such as Hastelloy gate valves, special steel gate valves and special alloy gate valves. To transport and process strong corrosive media, duplex stainless steel gate valves or super stainless steel gate valves are usually used to alleviate the problem, because they can work well in areas with corrosive environments.
