Ductile iron has much stronger mechanical properties than ordinary cast steel.
Ductile valves also have a wide range of operating pressures and temperatures, and are more economical than stainless steel valves. In response to market demands, KITZ group have a lineup of bellows seal valves, and the standardized ductile valves used in water, air, gas, oil, and other applications.
Operational Range and Applications
- Supported Media: Water, steam, air, gas, oil, and building/factory production equipment lines
- Pressure & Temperature: Varies by series (e.g., standard industrial uses span wide operational ranges; specific butterfly configurations like the HRDJ series handle maximum service pressures up to 1.0 MPa and temperatures from -20℃ to +120℃ with EPDM seats).
- Size Range: Typically ranges from 8mm to 500mm (1/4 inch to 20+ inches) depending on the specific product line
