Ceramic Valve Balls

Valve Balls

TongBall precision alumina/zirconia ceramic valve balls, suitable for extreme abrasion, corrosion and high temperature condition (alumina and heat-resistant up to 1500 ° C). Through advanced powder metallurgy and sintering control, ultra-high hardness (≥HRA 85) and chemical inertness are achieved.Patented ultra-finishing brings a near mirror surface, significantly reducing friction and medium adhesion, lasting competent mud, powder and reinforced fluid, beyond the performance of metal alloys.
