3 piece ceramic ball valves have same structure like general soft seated and metal seated 3 piece ball valve, except material of ball and seats are replaced by advanced ceramics. Because of the good properties of advanced ceramics, 3 piece ceramic ball valves can replace most common soft seated and metal seated ball valves in corrosive and abrasive applications 

1. 3PC body design: 3-PC body With middle body and two adapters, as following detailed drawing illustrated. The valve body has an integral ISO 5211 mounting pad ,so lever, pneumatic actuators and electric actuators can be assembled onto valve directly and easily. Well ground ceramic ball and seats ensure operating torque of 3 piece ceramic ball valves is much lower than general ball valves, smaller actuators can drive it and cost is saved.

Ceramic-to-Ceramic spherical seated: The perfect spherical seal between fine ceramic ball and seats ensure that 3 piece ceramic ball valves have a Class VI shutoff. The anti-scratch design between ball and seat, which prevent the deep sealing surface from being marred and scratched by particles.
