Abstract:
A fluid valve has a valve body with a valve seat for receiving a valve disc to close the valve. The valve seat is iron or steel. The valve disc is made of zirconium and has a zirconium oxide layer on disc surface which seats against the valve seat when the valve is closed. The valve has remained in a corrosive service for over six months where the original iron valves not having an oxide coated zirconium disc only lasted a few days.
