2026 Price Reference for Explosion-Proof Electric Globe Valve DN80 (CT6)

As of 2026, the price of a DN80 explosion-proof electric globe valve with CT6 rating generally ranges from RMB 4,800 to RMB 12,000, depending on body material, actuator configuration, and certification requirements .

- Cast steel (WCB) body models – Prices range from approximately RMB 4,800 to RMB 7,500. This is the most common and cost-effective configuration for general industrial applications. For example, a J941H-25C DN80 model from a domestic brand is listed at approximately RMB 4,060 . A branded intelligent switch-type J941H-16C DN80 is priced around RMB 4,500 .

- Stainless steel (304/316) body models – Prices range from RMB 7,000 to RMB 12,000. Stainless steel bodies provide superior corrosion resistance for aggressive chemical environments. A J941H-16P DN80 stainless steel explosion-proof globe valve is priced at approximately RMB 3,750 . Another brand lists a DN80 stainless steel motorized globe valve at approximately RMB 6,800 .

- Premium configurations – Electric actuators with modulating control (4-20mA signal), intelligent fail-safe functions, or IP68 outdoor protection add 10% to 30% to the base price. Modulating type models range from RMB 6,500 to RMB 9,000, while intelligent fail-safe types range from RMB 9,000 to RMB 12,000 .

It is important to note that CT6-grade explosion-proof actuators are typically 20% to 30% more expensive than lower BT4-rated equivalents due to the stringent manufacturing and certification requirements .

Understanding the CT6 Explosion-Proof Rating

The CT6 designation is one of the highest explosion-proof classifications available, representing the most stringent safety requirements for equipment used in hazardous areas.

C refers to the gas group. Group IIC includes the most flammable and explosive gases, such as hydrogen and acetylene, requiring the highest level of protection .

T6 refers to the temperature class. T6 means the equipment's maximum surface temperature under any operating condition does not exceed 85°C. This is the lowest and safest temperature class, significantly lower than T4's 135°C, making CT6-rated equipment suitable for use with gases that have very low auto-ignition temperatures .

The full explosion-proof marking for a CT6 actuator is typically Ex d IIC T6 Gb, indicating a flameproof enclosure (Ex d) suitable for explosive gas atmospheres (Group II, IIC gases) with a maximum surface temperature of T6 .

Key Factors Influencing the Price

Valve Body Material – The choice between cast steel (WCB) and stainless steel (304/316) is the most significant cost driver. Cast steel is suitable for steam, water, and general non-corrosive media; stainless steel is required for corrosive chemical applications .

Explosion-Proof Grade – CT6 certification is higher and more expensive than BT4. CT6 requires more stringent flameproof joint designs and rigorous testing, increasing manufacturing costs by approximately 20% to 30% .

When selecting this valve, pay careful attention to the explosion-proof certification (verify Ex d IIC T6 Gb), body material (WCB or stainless steel), actuator configuration (on-off or modulating), and protection grade (minimum IP67). Always request the actual explosion-proof certificate and confirm the valve is integrally designed for explosion protection. Investing in a correctly specified CT6 explosion-proof electric globe valve is not merely a purchase—it is an investment in operational safety, regulatory compliance, and the long-term reliability of your hazardous area processes.
