FREE-VALVE Two piece Flange End Ceramic Lined Floating Ball Valves are designed with engineering ceramics the engineering ceramics internal parts provide excellent wear resistance.The body of a two-piece ball valve is composed of a main body and a secondary body. After the ball , seat, and stem are installed in the main body, the secondary body is connected to the main body through nuts or bolts. 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 2pc ball valve consists of two separate pieces that can be easily taken apart for maintenance or repairs.
- 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.
- 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.
