Detailed Description
Pneumatic Ceramic Lined Floating Segment Control Ball Valves feature a V-port ceramic ball that provides precise throttling control during the valve's operation. This design allows for highly accurate and flexible adjustment performance. The self-lubricating capability of engineering ceramics ensures a superior seal after polishing. During operation, the V-shaped channel and ceramic seat create a wedge-shaped shearing effect, capable of cutting through fibers and particles within the media, preventing the ball core from sticking.
Key Features
- High Material Hardness: Ceramic material hardness exceeds HRC80.
- Precise Flow Control: Approximate equal percentage flow regulation, effective even at small openings.
- Flexible Operation: Fast adjustment speeds, large adjustable range, and simple maintenance.
- Straight-Through Design: No flow blocking elements in the valve cavity ensures smooth media passage.
- Self-Cleaning: ZrO2 ceramic balls possess excellent self-cleaning properties.

Applications
These Pneumatic Ceramic Lined Ball Valves serve a dual purpose, functioning both as reliable On/Off valves and as precise equal percentage throttling control valves. They are ideally suited for handling challenging media including water, steam, oil, lime slurry, liquid chlorine, nitric acid, acetic acid, oxidizing substances, and urea.
Frequently Asked Questions
What are the advantages of ceramic lining in ball valves?
Ceramic linings offer exceptional hardness (over HRC80) and resistance to corrosion and wear, making them far more durable than traditional metal valves when handling abrasive or corrosive slurries.
What is the "shearing effect" mentioned in the description?
The V-shaped ball design against the ceramic seat acts like a pair of scissors. It can cut through fibers and solid particles in the media during closing, which prevents the valve from jamming.
Can these valves handle high-temperature industrial media?
Yes, these valves are designed for high-temperature applications, with a standard operating range up to 200ºC.
Is the flow control accurate for small openings?
Absolutely. The V-port design provides an equal percentage flow characteristic, ensuring precise and stable throttling even when the valve is only slightly open.
Are the connection sizes customizable?
Yes, while standard sizes range from DN25 to DN200, face-to-face dimensions and flange connection sizes can be customized to meet specific site requirements according to various international standards.
What driving modes are supported for this valve?
This specific series is equipped with a pneumatic actuator for automated control, though the valve structure itself is highly adaptable for various industrial control systems.
