Industrial Valve Flange End V Port Pneumatic Ceramic Segment Control Ball Valve For Lithium battery industry
FREE-VALVE pneumatic ceramic lined segment control ball valves are that V-port ceramic ball provides precise throttling control in the valve’s opening and closing, with more accurate and flexible adjusting performance.Besides,the self-lubricating capability of engineering ceramic ensures the good sealing after polishing,during the opening and closing process
FREE-VALVE Industrial Valve Flange End V Port Pneumatic Ceramic Segment Control Ball Valves are that V-port ceramic ball provides precise throttling control in the valve’s opening and closing, with more accurate and flexible adjusting performance.Besides,the self-lubricating capability of engineering ceramic ensures the good sealing after polishing,during the opening and closing process,the V shaped channel of the ball and ceramic seat have a wedge-shaped shearing effect,which can cut off fibers and particles in media during the opening and closing process to prevent the ball core from sticking.
Features:
- The hardness of the ceramic material can be higher than HRC80.
- Approximate equal percentageflow regulation characteristics and works at small opening.
- The flow adjusting more accurately and flexibly,with large adjustable range,fast adjustment speed,simple maintenance.
- Straight-through design, no flow blocking element in the valve cavity.
- ZrO2 ceramic ball have good self-cleaning property.
