FREE-VALVE V-notch ceramic segment ball valve has a ceramic ball with contoured v-notch segment for accurate flow regulation and tight shutoff . The v-notch ball design features positive shearing action and process an inherent equal percentage precise flow characteristic in extremely corrosive environments containing abrasive solid particles.
Features:
- The V notch ceramic ball valves are quarter-turn valves.
- The hardness of the ceramic material can be higher than HRC80.ZrO2 ceramic ball have good self-cleaning property.
- 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.
- Body material could be carbon steel, stainless steel according to working condition and seat is structure ceramics, so that sealing face will not be eroded, performance during long-time usage.
- V notch ceramic ball valvesutilize a three-piece design structure, enabling the ceramic ball and seat to achieve free centering
