Product Description
FREE-VALVE Pneumatic Ceramic Lined Floating 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. 
Technical Specification
Note: Our company also produces other pressure grade products, flange connection size according to customer requirements according to GB/T9113 ,ASME B16.5 or JIS B2220.
FREE-VALVE Pneumatic Ceramic Lined Floating Segment Control Ball Valves can serve dual purpose,functioning both as an On/Off Valve and as a precise equal percentage throttling control valve,the valves are suitable for water,steam,oil,lime slurry,liquid chlorine,nitric acid,acetic acid,oxidizing substances,urea and other medium.
- The hardness of the ceramic material can be higher than HRC80.
- Approximate equal percentage flow 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.
