WCB WCC Worm gear segmented ball valve structure introduction:
WCB WCC Worm gear segmented ball valve has the V type gap in the valve plug which will do wedge-shaped sheared action when the WCB WCC Worm gear segmented ball valve is closed, which not only has self-cleaning function but also can prevent being stuck from the dirt between plug and seat.WCB WCC Worm gear segmented ball valve is not only for the general media but also special for controlling the medium of slurry, drainage, fiber and small particles.
WCB WCC Worm gear segmented ball valve equipped with pneumatic or electric actuator can meet various control requirements, WCB WCC Worm gear segmented ball valve is widely used in the control systems of electric power, petroleum, chemical, metallurgy and papermaking.

Structure	Segment ball
Nominal Diameter	Wafer type 1/2”~10” (DN15~DN250), Flange type: 1”~28”(DN25~DN700)
Pressure Rating	ASME Class 150 ~ CLASS 300/ PN10-PN40
Connection	Flange Type (RF、RTJ、FM）、Wafer type

WCB WCC Worm gear segmented ball valve design feature:

· Hard treated trim parts, which is grinded, polished, of high degree of finishing and wear resistance.
· The cavity is designed based on straight through and streamline type, which can prevent blocking up and improve the steady of action.
· Shearing action ball and the valve can clean itself, which is suitable for various kinds of gas and liquid and especially for the liquid of containing paper pulp, sewage and containing solid particle.
