Flanged Carbon Steel Ball Valve Description
The main material of flange carbon steel ball valve is carbon steel, which has good corrosion resistance and mechanical properties and is suitable for harsh conditions such as high temperature and high pressure.Flange carbon steel ball valves are widely used in petroleum, chemical, natural gas, electric power, metallurgy, papermaking, food, medicine, environmental protection and other fields, especially in high pressure, high temperature and highly corrosive media.
Flanged Carbon Steel Ball Valve specification
- Nominal diameter: DN15–DN800 (limited by casting process);
- Pressure level: PN1.6–PN32.0 (Class 150–2500);
- Applicable temperature:
- Soft seal: -29℃ ~ 200℃ (PTFE valve seat);
- Hard seal: -196℃ ~ 550℃ (metal seal);
- Leakage level: Meets ANSI VI level zero leakage (API 598 standard);
- Connection standard: Flange end complies with ASME B16.5
Flanged Carbon Steel Ball Valve
Features
Low flow resistance and energy saving
Full-diameter design, the flow resistance coefficient is only 1/10 of the same-caliber gate valve, reducing pumping energy consumption by 12-18%; Reliable sealing
When the ball and the valve seat are closed, the sealing surface is protected by the medium, and the anti-scouring life is >100,000 times of opening and closing;
Convenient operation
90° rotation fast opening and closing (0.05-0.1 seconds), supporting automatic control;
Safety redundancy
Fireproof design (API 607), anti-static device and valve cavity pressure relief function.
Advantages
Strong economy
Carbon steel costs less than stainless steel, and has low maintenance costs (seals can be quickly replaced);
Pressure and temperature resistance
Burst pressure ≥ 4 times rated value, high temperature strength retention rate > 80% (550°C);
Multi-function adaptability
Compatible with granular media (solid content ≤ 5%), supports DCS remote control;
Long life design
Surface galvanizing/spraying treatment, corrosion resistance life > 10 years
