Cemented carbide valve seats are commonly manufactured using powder metallurgy techniques. Metal powders, along with other additives, are mixed, pressed, and sintered to create the valve seat. This manufacturing process ensures a uniform structure and excellent physical properties of the hard alloy valve seat.

These valve seats are widely employed in industries such as petroleum, chemical, power generation, and metallurgy, where they are utilized for controlling the flow of fluids. Due to their outstanding wear resistance and corrosion resistance, hard alloy valve seats significantly prolong the valve's lifespan and enhance the system's reliability.

A carbide valve seat is a valve component with high hardness, wear resistance, and corrosion resistance. It is extensively used in industries dealing with high temperatures, high pressures, and corrosive media to ensure efficient fluid control and enhance system performance.

The hard alloy valve seat is a layer of hard hard alloy welded on the valve body seat, so that the sealing surface has high wear resistance and scratch resistance. This material is especially suitable for applications where the media is warm and dry.

The material of the sealing surface of the cemented carbide seat is usually selected from cobalt-based and nickel-based alloys, and the matching surface is usually plated with similar materials, but with poor hardness to reduce scratches during work. However, the matching two sides are not always of the type of overlay welding, which type depends on the performance of the cemented carbide used.
