Tungsten Carbide Spherical Valve Seat

Product Description

The tungsten carbide spherical valve seat is the core component in ball valves that cooperates with the ball to achieve sealing. The spherical valve seat is in full circumferential contact with the sphere, and the sealing stress distribution is uniform. Therefore, it can withstand high-pressure sealing environments and requirements in petroleum, chemical, and other working conditions through full circumferential contact.

Moreover, by using hard alloy as its material, the hardness, density, and corrosion resistance of the valve seat have been greatly improved. Therefore, the geometric shape and material of the hard alloy spherical valve seat enable it to achieve longer service life and lower maintenance costs. It can also maintain good sealing performance in high-pressure, high-frequency, and harsh medium scenarios.

Features of Tungsten Carbide Spherical Valve Seat

The spherical valve seat is in 360°contact with the sphere, with full circumferential contact.

Features of Tungsten Carbide Spherical Valve Seat

Suitable for high-pressure conditions such as oil and gas industry, chemical control valves, etc.
