Chengxin Valve's JIS Bronze Globe Valve delivers precision flow control for industrial plumbing systems, combining Japanese Industrial Standards compliance with robust bronze construction. Engineered with DN15-DN100 sizing and strict JIS B2031 face-to-face dimensions, this valve ensures leak-proof performance in demanding environments. With ISO-certified manufacturing since 1993, our valves offer reliable shut-off capability and corrosion resistance for water, steam, and non-aggressive fluid applications.
Core Technical Specifications:
| Feature | Specification |
|---|---|
| Body Material | Bronze (CAC406) |
| Pressure Rating | JIS 10K Standard |
| Temperature Range | -20°C to 200°C |
| End Connection | Flanged (JIS B2210) |
Key Performance Advantages:
✓ Precision Flow Regulation – Linear stem movement enables accurate flow adjustment
✓ Corrosion Resistance – Bronze construction withstands water corrosion and scaling
✓ Zero-Leak Design – Graphite-packed gland prevents stem leakage
✓ Maintenance-Friendly – Top-entry design enables seat replacement without pipe disassembly
✓ Dimensional Compliance – Exact JIS B2031 face-to-face ensures interchangeability
Industrial applications include water treatment plants, HVAC distribution systems, boiler feed lines, and industrial process piping. The non-rising stem design maintains operational clearance in confined spaces, while the renewable disc-seat arrangement extends service life beyond standard valves.
Detailed Technical Parameters:
| Nominal Size (DN) | Face-to-Face (mm) | Flow Coefficient (Cv) | Weight (kg) |
|---|---|---|---|
| 15 | 130 | 1.2 | 0.8 |
| 25 | 160 | 3.8 | 2.1 |
| 50 | 230 | 14.0 | 7.5 |
| 80 | 310 | 34.0 | 18.2 |
| 100 | 350 | 52.0 | 28.7 |
Customization options include extended bonnets for high-temperature service, stainless steel trim for corrosive media, and lockable handwheel configurations. All valves undergo hydrostatic shell testing at 1.5x rated pressure and seat leakage testing per MSS SP-61 standards.
Enhanced Operational Benefits:
• Reduced Maintenance Costs – Renewable seat ring extends valve life cycle by 40% compared to standard designs
• Energy Efficiency – Precision-machined disc minimizes pressure drop across the valve
• Installation Flexibility – Bidirectional flow capability simplifies piping configuration
• Supply Chain Reliability – Standard DN15-DN100 sizing ensures replacement availability
