Tungsten Carbide Valve Balls

We are esteemed exporter of Tungsten Carbide Valve Balls in Zhuzhou, Hunan, China. Tungsten carbide valve ball is an important part of globe valve , globe valve can make use of the handle or other drive means rotating sphere 90. So that the hole of the ball and the valve overlap or vertical centerline of the channel, to achieve the valve fully open or fully closed action, usually working in harsh environments. tungsten carbide valve ball with high hardness, wear resistance, corrosion resistance and high temperature, etc., and therefore mainly used in all kinds of sealing work, such as: pump, thermal power plant ash slagging water systems, fluid seal rotating ball.

Tungsten carbide valve ball for conventional pump
Valve ball, the role of a one-way valve to control the flow of oil flow, is in a very poor conditions of work. Multi-component working medium is air, water, oil, sand, wax, resin and asphalt, is a random change and non-uniform three-phase medium. Pumping liquid carry some mechanical impurities at high speed flows violently scour the ball, the ball and seat, has produced hit between the hood, a large quantity of oil wells in the sand, make the ball and seat sealing surface between the damage more rapidly, this damage is a mechanical wear. In most wells all contain corrosive medium, which valve ball is particularly serious corrosion damage.
