Price Reference for DN80 CT6 Safety Valve
Prices for DN80 explosion-proof safety valves vary significantly based on material grade and configuration:
Standard A48Y-40 series DN80 safety valves from established domestic brands are available from approximately 1,491 to 2,300 CNY depending on pressure rating and supplier .
Stainless steel configurations such as A28Y-16P DN80 command premium pricing at approximately 6,182 CNY, reflecting enhanced corrosion resistance for aggressive media .
High-pressure configurations such as A48Y-64C DN80 with higher pressure ratings range to approximately 9,469 CNY .
For comparison, standard non-explosion-proof A41Y-25C DN80 valves are listed at approximately 2,759 CNY, serving as a baseline reference .
Key factors affecting price include explosion-proof certification (CT6 vs lower temperature classes), body material (carbon steel vs stainless steel), pressure rating, and connection type.
Understanding CT6 Explosion-Proof Classification
The CT6 classification is the highest level in explosion-proof temperature grading. Exd II CT6 indicates flameproof enclosure design for IIC gas groups with T6 temperature class (maximum surface temperature ≤85°C) . CT6 is the strictest temperature classification, making the valve suitable for the most hazardous environments where explosive gases such as hydrogen, acetylene, and carbon disulfide may be present .
Technical Specifications
DN80 explosion-proof safety valves typically feature spring-loaded design with flanged connections . Body materials include carbon steel (WCB) for standard service and stainless steel (CF8/CF8M) for corrosive applications . Pressure ratings range from PN16 to PN64 depending on application requirements. Set pressure ranges are configurable based on system protection requirements.
Hazardous Area Applications
DN80 CT6 explosion-proof safety valves serve critical functions in oil and gas processing facilities, petrochemical plants, flammable gas storage systems, and hydrogen handling applications requiring maximum temperature safety.
Summary
DN80 explosion-proof safety valves with CT6 certification provide maximum safety for hazardous area overpressure protection, with prices ranging from approximately 1,491 CNY for standard carbon steel models to over 9,469 CNY for high-pressure configurations. The CT6 classification ensures surface temperatures remain below 85°C, representing the highest level of explosion-proof safety. Selection requires careful evaluation of set pressure, temperature classification, and material compatibility based on specific hazardous area requirements.
