Stainless Steel Mini Ball Valve
Stainless Steel Mini Ball Valve is a compact, high-performance shut-off valve designed for precise flow control in small-bore piping systems. Made from premium 304 stainless steel, these valves feature a quarter-turn handle for fast, reliable operation and are available in male-to-male, male-to-female, and female-to-female configurations. With a pressure rating of PN63, they deliver leak-tight performance in a wide range of industrial, commercial, and domestic applications.
【Size】DN6~DN20
【Material】SUS304, SUS316L
【Sealing】PTFE
Key Features
- Compact & Lightweight Design: Miniature size allows installation in tight spaces, ideal for small-bore piping systems and equipment integration.
- Quick Quarter-Turn Operation: 90-degree handle rotation provides fast, easy on/off control with minimal effort.
- High Pressure Resistance: PN63 pressure rating ensures reliable performance in high-pressure fluid and gas systems.
- Superior Corrosion Resistance: 304 stainless steel construction offers excellent resistance to rust, corrosion, and most common chemicals, ensuring long service life.
- Leak-Tight Sealing: Precision-machined ball and seat provide a secure, bubble-tight seal, preventing fluid/gas leakage.
- Versatile Configurations: Available in male-to-male, male-to-female, and female-to-female thread connections to suit diverse installation needs.
- Durable & Low Maintenance: Robust stainless steel body and wear-resistant components require minimal maintenance, reducing operational costs.
