Product description
Cemented carbide valve seat are typically used in conjunction with carbide balls. Cemented carbide, the primary material used in cemented carbide seats, is corrosion and abrasion resistant and can withstand high pressures.Our precision polished tungsten carbide valve seats are made of 100% virgin raw materials, with high hardness carbide. Carbide valve seats are used in a variety of sizes and configurations and can be used under abrasive, corrosive and aggressive conditions and are used in many applications such as drilling for oil and gas, geotechnical mining and fluid control.
The following are the outstanding features of Tungsten carbide valve seats:
l Corrosion and wear resistance.
l Longer operating time.
l Resistance to high pressure.
l High accuracy of dimensions.
l Excellent tolerance to thrust loads and high temperatures.
