  • products details
Si3N4 Silicon Nitride ceramic has extreme high hardness and chemical stability against almost all chemical solvent. Moreover Si3N4 ceramic has stronger high temperature resistance and thermal shock resistance than Al2O3 and ZrO2 ceramic.

Si3N4 Silicon Nitride ceramic ball valves are used in abrasive and corrosive applications which also have high pressure and high temperature working conditions. 

Si3N4 Silicon Nitride ceramic ball valves solve abrasion and corrosion problem under high pressure and temperature. They have much longer service life and much less maintenance cost than steel ball valves.

Why Ceramic Valves?

1. Excellent abrasion resistance many times higher than steel duo to extremely high hardness
2. Outstanding corrosion resistance against almost all organic and inorganic solvents
3. Much longer service life, much less maintenance and downtime
4. Stable, inert, no contamination to medium

Why Choose YFL?

1. Experienced in providing best solutions according to various sever working conditions to solve problems
2. Strict quality control from ceramic raw materials production, ceramic parts machining to pressure test and function test
