FREE-Valve Brand WCB Bare stem Ceramic Lined Ball Valves are designed with engineering zirconium ceramics ,the engineering zirconium ceramics internal parts provide excellent wear resistance, the ceramic ball valves are widely used as an open and close function as well as a throttling control tasks in corrosive medium with abrasive solids content.
Features:
- The hardness of the ceramic material can be higher than HRC80.Engineering internal parts of ceramic ball valve provide superior protection from corrosive and abrasive medium.
- Customized actuation types are installed on the ceramic ball valve, the manual lever or gear box, as well as with pneumatic, electric and hydraulic actuators.Customized V type ceramic control valve is also available for us.
- The valve has a floating ball design, the ball is floating, the ball has a defined clearance and is pressed against the downstream seat under the differential pressure to achieve sealing.
