â… . Product Introduction
The 3-Pieces Ceramic Ball Valve is an industrial valve that uses a rotating ceramic ball to control the on-off of fluid flow. Only the trim components, including the ball and seat, are made of ceramic material. It is designed for quick shutoff, distribution, and redirection of media in pipelines.
This valve features a compact three-piece body design. It can achieve a tight seal with just a 90° rotation and minimal operating torque. Its full-port, straight-through flow channel ensures low flow resistance and unobstructed media passage.
The 3-Pieces Ceramic Ball Valve is ideal for handling abrasive, corrosive, and particulate-laden media such as lime slurry, seawater, and particles. It is widely used in harsh operating environments including mining, petroleum, petrochemical, power generation, and papermaking industries. It is also suitable for water treatment, gas pipelines, and steam boiler systems.
â…¡. Product Features
- Excellent Wear & Corrosion Resistance: The ceramic ball and seat provide exceptional resistance to abrasion, scouring, and chemical corrosion, ensuring a long service life even with harsh media.
- Quick & Easy Operation: A 90° rotation of the handle is all that is needed to fully open or close the valve, requiring minimal torque for smooth, fast operation.
- Low Flow Resistance: The full-port, straight-through flow design minimizes pressure drop and allows for unobstructed media flow.
- Compact & Maintainable: The three-piece body structure enables easy disassembly for inspection, maintenance, and replacement of internal components without removing the entire valve from the pipeline.
- Reliable Sealing: The ceramic-to-ceramic sealing surface ensures a tight, long-lasting seal, reducing the risk of leakage over time.
- Broad Application Range: Suitable for a wide variety of media and operating conditions, from clean gases and liquids to abrasive slurries and particulate matter.
- Customizable Design: The valve can be customized with different materials, pressure ratings, and actuation options to meet specific customer requirements.
