Steam Process Mastery: COVNA Industrial Valve Solutions
As global industries accelerate decarbonization, steam remains a critical energy medium with 68% of industrial heating relying on steam systems (IEA 2023). COVNA delivers precision-engineered steam valves that empower safe and efficient thermal energy transfer across temperature ranges from 150°C to 580°C.
Mission-Critical Steam Applications
1. Oil & Gas Refining
Catalytic Cracking: High-pressure steam control valves (ANSI Class 150-2500) for FCCU reactor-regenerator systems
Pipe Tracing: Self-acting thermostatic steam traps maintain optimal viscosity in heavy crude pipelines
Tank Heating: Pilot-operated steam regulators with ±0.5 bar pressure stability
2. Chemical Processing
Reactor Jacket Heating: Triple-offset steam isolation valves with 100,000+ cycle durability
Distillation Columns: Multi-stage pressure reducing stations with anti-water hammer design
Heat Exchangers: Steam control valves with condensate drainage ports (Kv: 5-450)
3. Pulp & Paper Manufacturing
Yankee Dryer Systems: ASME B16.34 certified steam valves for 20 bar dryer drum operations
Black Liquor Recovery: Lined plug valves resisting caustic condensate (pH 12-14)
Tissue Drying: Fast-acting (≤1s) solenoid valves for steam shower systems
4. Cross-Industry Thermal Management
Pharmaceutical CIP/SIP processes
Food & Beverage sterilization autoclaves
Rubber vulcanization line steam control
