Description
1. Overview of Stainless Steel Threaded Ball Valve
VTON stainless steel threaded ball valves are engineered for efficient and durable flow control. Manufactured with precision using advanced casting technology, these valves are suitable for applications in water supply systems, oil pipelines, chemical processing, and more. The elastic sealing structure and robust design ensure reliable operation and extended service life.
2. Features
- Advanced Casting: High-quality casting ensures a reasonable structure and attractive appearance.
- Elastic Sealing: The elastic sealing seat provides a reliable seal and smooth operation.
- Inverted Seal Design: The bottom-mounted valve stem with an inverted seal prevents impact during abnormal pressure increases.
- Compact and Lightweight: Simple structure, lightweight, and small installation size make these valves easy to install and operate.
