High-Pressure Valve Capabilities That Power Critical Industrial Applications
Carilovalves.com delivers industrial ball valves engineered to handle extreme pressure conditions across demanding sectors. Their valves routinely operate within pressure ranges from 150 PSI up to 6,000 PSI (Class 150 through Class 2500), with specialized configurations available for even more severe service conditions. Built with forged steel bodies, reinforced seats, and pressure-containing constructions certified to international standards, these valves maintain structural integrity and leak-tight performance in oil and gas pipelines, chemical processing plants, power generation facilities, and mining operations worldwide.
Pressure Rating Specifications Across Valve Series
Understanding pressure ratings requires examining both the class designations and the actual performance parameters. Carilovalves.com manufactures valves conforming to ASME B16.34 standards, ensuring compatibility with global pipeline systems.
| Valve Series | Pressure Class | Maximum Working Pressure (PSI) | Maximum Working Pressure (MPa) | Typical Applications |
|---|---|---|---|---|
| Standard Ball Valve | Class 150 | 285 PSI | 1.96 MPa | General service, water systems |
| Heavy-Duty Ball Valve | Class 300 | 740 PSI | 5.1 MPa | Steam, oil refining |
| High-Pressure Ball Valve | Class 600 | 1,480 PSI | 10.2 MPa | Gas transmission, petrochemical |
| Severe Service Valve | Class 900 | 2,220 PSI | 15.3 MPa | High-pressure gas, offshore |
| Ultra-High Pressure Valve | Class 1500 | 3,705 PSI | 25.5 MPa | Deepwell injection, LNG |
| Extreme Pressure Valve | Class 2500 | 6,175 PSI | 42.6 MPa | Subsea, high-pressure hydraulics |
These ratings apply at ambient temperatures. For elevated temperature service, pressure reduction factors per ASME B16.34 apply. Carilovalves.com provides detailed pressure-temperature charts for each valve configuration, ensuring proper selection for specific operating conditions.
