Tungsten Carbide valve stem and seat

Tungsten carbide valve stem and seat

Similar cemented carbide valve stems and seats are primarily used in the petroleum extraction industry under harsh conditions. They serve as critical components for controlling flow in certain specialized valves. Due to the environmental demands, these valve stem and seat combinations require exceptional resistance to wear and corrosion.

1.Material:Tungsten carbide tips and stainless steel(304,316,304L,316L) body.( which provides optimum wear resistance in erosive conditions.)

2.Various kinds of cermented carbide grades are available for the tips.

3.Size:usually made as customer's drawings.

4.HIP sintering,good compactness,stable chemical properties.

5.Factory's offer

6.Advanced production line and inspection equipments to ensure high quality products.

Hardened alloy steel stems and seats are widely used in adjustable needle valves and positive choke valve assemblies. However, many of our domestic and international customers tend to prefer our adjustable choke valve stems with sintered cemented carbide tips. The overall sintered solid carbide tips, combined with our special structural design, makes our tungsten carbide choke valve stems more wear-resistant, corrosion-resistant, with longer service life, reducing replacement costs. Therefore, they are more welcomed by customers.And the matching valve seats, because they are made of integral tungsten carbide material,its advantage is more obvious.
