FREE-VALVE brand Pneumatic Ceramic Ball Valves are designed with engineering ceramics. The engineering ceramics internal parts provide excellent wear resistance and corrosive 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:

1.The hardness of the ceramic material can be higher than HRC80.

2.Engineering internal parts of ceramic ball valve provide superior protection from corrosive and abrasive medium.

3.Pneumatic operated save the cost of man power .

4.Customized V type ceramic control valve is also available.

5.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.
