Tungsten Carbide Valves assemblies parts are widely used on a choke valve in oil gas industry or 

other energy industry.Tungsten Carbide Valves assemblies parts are specifically designed to resist corrosion, 

abrasion, wear, fretting, sliding wear and impact both onshore offshore and surface subsea applications.

Our complete line of high-performance tungsten carbide based anti-wear hard-facing and integral products 

will help you to find the best solution for effectively eliminating your abrasion problems.

They are widely used for valves. Two adjacent disc each containing twp precision holes(orifice). 

The front disc floats against the back disc creating a mated interface and assuring a positive seal. 

The disc type valve uses two Tungsten Carbide discs with holes of specific geometry. 

The upper disc is rotated relative to the lower disc (manually or by actuator) varying the orifice size. 

The discs are rotated 180 degrees between open and closed position. In addition, 

the lapped matting surfaces of the discs designed to provide positive seal.

Products advantages：

1. Sufficient strength and rigidity.

2. Good impact toughness.

3. Abrasion resistance.

4. Corrosion resistance.

5. Long service life.

6. Anti-compression.

7. Excellent thermal shock resistance.

8. Good sealing character.
