Cast Floating Ball Valve Supplier in India
For general industrial applications where dependable shut-off and ease of operation are required, cast floating ball valves are widely used due to their practical design and cost efficiency. The casting process allows the valve body to be produced in various sizes and configurations, making it suitable for a broad range of service conditions.
As a Cast Floating Ball Valve Supplier in India, these valves are supplied for systems that require reliable isolation with consistent sealing performance. The floating ball design ensures that the sealing force increases with line pressure, providing effective shut-off during operation.
How Cast Floating Ball Valves Work
The valve uses a ball that is supported by seats rather than being fixed in position. When fluid enters the valve, the pressure pushes the ball against the downstream seat, creating a seal.
Rotating the stem turns the ball inside the valve body, allowing the bore to align with the pipeline for flow or block it completely. This simple mechanism enables quick operation while maintaining effective sealing.
Benefits of Cast Floating Ball Valves
- Reliable sealing due to pressure-assisted seat contact
- Simple internal design for easy maintenance
- Suitable for a wide range of general industrial applications
- Quick quarter-turn operation for fast shut-off
- Cost-effective compared to forged alternatives
- Compact structure for efficient installation
Design Standards
Cast floating ball valves are manufactured in accordance with international standards to ensure durability and performance consistency:
- API 608
- API 6D
- ASME B16.34
- BS 5351
Inspection and Testing Standards
Each valve is inspected and tested to verify sealing capability and structural integrity:
- API 598
- Hydrostatic shell and seat testing
- Visual and dimensional inspection
