Casting gate valves are one of the most commonly used types of valves in various industries, including oil and gas, petrochemical, power, and water treatment.

This type of valve is used to control the flow of fluid through a piping system or pipeline. Basically, a gate valve has a gate or wedge that moves vertically inside the body of the valve to either open or close the valve.

The casting gate valves are made of high-quality cast iron, stainless steel, or carbon steel, and are durable and long-lasting.The size and pressure range of casting gate valves vary according to the requirements of the application. They are available in a wide range of sizes, from small diameter valves that are used for residential plumbing applications to larger industrial sizes that can handle high volume and high-pressure systems.

Typically, the pressure ranges of casting gate valves are from 5 bar to 400 bar, and the sizes range from 1/2 inch to 60 inches.

Casting gate valves have a wide range of applications. They are used in the oil and gas industry to control the flow of crude oil, natural gas, and other petroleum products in pipelines and processing plants. In the petrochemical industry, casting gate valves are used to control the flow of chemicals and other liquids. They are also used in power plants to control the flow of steam and water in boilers and turbines. Other applications of casting gate valves include water treatment plants, wastewater treatment plants, and other industrial facilities.The choice of material for casting gate valves depends on the application and the type of fluid being transported. Cast valves are commonly used for low-pressure applications, while stainless steel and carbon steel valves are used for high-pressure applications. The choice of material also depends on the chemical compatibility with the fluid being transported.In summary, casting gate valves are versatile and durable valves that are widely used in various industries. They come in different sizes, pressure ranges, and materials to serve different applications. These valves are essential components of piping systems and play a critical role in controlling the flow of fluids.

Other remarks 1

Through improving the structural design and selecting reasonable packing structure and qualified packing supplier, the valves can meet the Class A sealing test requirements of ISO 15848 FE.

Other remarks 2

The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good.

Other remarks 3

Rising stem structure, making the valve switch position be clear at a glance

Other remarks 4

The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced.

Other remarks 5

Small switching moment, reliable sealing

Other remarks 6

SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing

Other remarks 7

Small flow resistance, high flow capacity and good flow characteristics

Other remarks 8

For small gate valves, the interchangeability can be ensured with process tooling.

Other remarks 9

The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.

Design of Disc

Gate valves with NPS>=2 are flexible gate,gate valves with with NPS<2 are of solid gate.

If being requested by the customer,the Belleville spring loaded packing impacting system can be adopted for enhancing the durability and reliability of the packing seal.
