Product Description

Passivation YG20 Tungsten Carbide Choke Valve Seats

Tungsten carbide choke valve seats


Tungsten carbide choke beans are used to control the flow of fluids and are usually mounted on the tungsten carbide choke stem. They are widely used on a choke valve in oil gas industry or other energy industry.

Tungsten carbide parts have long since been used in the petroleum industry for fluid handling, valve balls, valve seats, flow control valves, carbide sleeves, etc. While steel and other materials were traditionally used to make these parts, tungsten carbide easily replaced the same with industries preferring to opt for it owing to the following features:

• High wear resistance
• Abrasion and corrosion resistance, even with high strength viscous oils and fluids
• High strength and toughness
• Dimensional stability
• Good finish


We make tungsten carbide choke beans, seats, balls and sleeves for more than 8 years. The quality feedbacks from our customers are very well. We do 100% inspection before shipment and material certificate and inspection report can be provided.
