The removable face part in the Ceramic Valve Seat is used to support the full closed position of the spool and constitute the sealing pair.General seat diameter is the maximum flow diameter of the valve.
Ceramic seat material composition:
· 95%--99.99% Alumina (Al2O3) · Silicon Carbide · Silicon Nitride
· TTZ: Magnesia partially stabilized Zirconia (ZrO2) · YTZP: Yttria partially stabilized Zirconia (ZrO2)
· ZDY: Yttria fully stabilized Zirconia (ZrO2)
The property of the Ceramic seat:
·Excellent physical & chemical stability ·High temperature resistance(up to1750℃)
·Excellent wear & pressure & corrosion& insulation resistance and thermal conductivity..
