High Precision Low Friction Wear Resistance Zirconia Ceramic Valve Seat

The main features of the zirconia ceramic valve seat
1.High density:  over 6 g/cm3, which makes it the densest body of the ceramic products
2.High hardness: over 9 on Mohs scale, diamond being 10, with a satin-smooth surface finish
3.High toughness: over 1200 MPa, approx. 4 times in comparison with 95% alumina
4. Excellent wear resistance, it's much better than aluminum oxide ceramics with longer life cycle
5. Low thermal conductivity:  less than 3 W/m.k at ambient temperature, so it's an ideal thermal material
6. Good chemical and corrosion resistance, it's equivalent to above 99% alumina

The description of the zirconia ceramic valve seat
Zirconia ceramic valve seat is a key part of the various pumps, valves in household appliances, electrical appliances, and industrial applications. It plays a decisive role in liquid, gas, oil sealing, and controlling performance. 

With zirconium oxide ceramic outstanding properties, such as wear-resistance, chemical resistance, low thermal conductivity, high thermal expansion coefficient similar as stainless steel, very low friction coefficient, zirconia ceramic seal rings have been creating a very positive impact on aging features, service life-span, productivity, dependability in industrial equipment, mechanical engineering, like the food and beverage industry, medical equipment, electrical devices and so on.

Besides the ceramic seal ring, we also produce a variety of customized ceramic valve seat, ceramic ball valve, ceramic valve disc, ceramic piston and plunger for fluid, gas, oil-controlling / regulating system.
