Miller supplies tungsten carbide balls, whose main characteristic is the very high hardness with consequent remarkable resistance to abrasion, tungsten carbide balls are normally used in special applications such as
Valves: The excellent wear and abrasion resistant properties of tungsten carbide balls are ideal for almost any valve application. Tungsten carbide valve balls and seats are evolved from the traditional cock valve. Its opening and closing parts are a sphere. The purpose of opening and closing is achieved by the sphere around the axis of the valve stem. They are widely used for sealing valves of oil pumps in petroleum drill and exploitation equipment and they are also one of the key components of the pump. Because of the harsh working environment and conditions in the petroleum drilling industry, it requires the valve balls and seats to have good sealing, wear resistance and corrosion resistance.
Miller is an ISO certified professional manufacturer for tungsten carbide valve balls & seats since 2008, and uniquely positioned to help you identify and source the correct carbide valve balls & seats for your application. They have high hardness, good resistance to wear and corrosion. The high precision deep processing, makes them perfect matching, and smoothness can reach mirror R0.4. Sizes could be customized, as we have a group of experienced technical personnel, advanced mould production equipments to realize your customization by drawing and sample.

Grade: Miller manufactured 4 main grade ( chemical composition) of carbide balls
1. WC92% + 8% Co (In request of more wear-resistance, we suggest to use WC-Co grades. )
2. WC92% + 8% Ni (In most corrosion-wear situations, an optimum choice is the WC-Ni grades, which are resistant down to pH 2 to 3.)
3. W85%-97%+Ni+Fe Tungsten balls (Density 15.5-18.5g/cm3, mostly are used in the field of shots and counterweight. such as the fish pendant, Oil drilling balance,Ball valves and bearings, Shotgun bullet, Armor-piercing bullet…)
4. W99.95% Pure tungsten balls (Density 19.0-19.2g/cm3, mostly are used in Aerospace, aviation, electrical Instrumentation, laboratory…)
