Price Reference for DN100 Explosion Proof Electric Gate Valves
Explosion proof electric gate valve prices vary based on material, pressure rating, and certification:
Standard carbon steel WCB electric gate valves with CT4/CT6 explosion proof actuator typically range in price based on configuration. CT6 rated actuators command a premium due to the more stringent temperature classification (T6 allows a maximum surface temperature of 85°C, the safest level).
Stainless steel SS304/SS316 valves with CT6 actuators for corrosive or food applications command higher pricing reflecting the advanced material specifications.
Premium models with full API compliance, NACE certification, and comprehensive documentation are available at competitive pricing from Chinese manufacturers.
Key factors affecting price include body material (WCB vs stainless steel), actuator type and power, certification scope, connection type (flanged vs welded), and CT6 temperature classification requirements.
Understanding CT6 Explosion Proof Rating
The CT6 rating is the highest temperature classification in the explosion proof certification system:
Temperature classification is critical for hazardous area safety. T6 is the strictest classification (surface temperature not exceeding 85°C) providing the highest level of safety for explosive atmospheres. ATEX/IECEx certification ensures compliance with international hazardous area standards. Valves may be certified for Zone 1 and Zone 2 (gas), Zone 21 and Zone 22 (dust), with corresponding gas groups IIA, IIB, and IIC.
Technical Specifications
Pressure and Temperature: DN100 valves are available in PN16, PN25, PN40, and Class 150/300 ratings. The explosion proof actuator maintains CT6 rating at the required operating temperatures, with maximum surface temperature not exceeding 85°C.
Materials: Cast carbon steel WCB is standard for general service, with LCB available for low temperature applications. Stainless steel CF8/CF8M is standard for corrosive service. Wedge and seat rings are hard-faced with Stellite 6 or 12 alloy for wear resistance.
Actuator Features: The electric actuator features an explosion proof enclosure per Ex d IIB T6 or Ex d IIC T6, with CT6 temperature classification for maximum safety. Multiple control options include modulating or on-off control and remote position indication.
Valve Design: Rising stem, bolted bonnet design provides full bore with flexible wedge for thermal compensation. Hard-faced seating surfaces ensure reliable shutoff.
Standards: API 600 for design, ASME B16.34 for pressure-temperature ratings, ISO 5211 for actuator mounting, and ATEX/IECEx for explosion proof certification.
Hazardous Area Applications
DN100 explosion proof electric gate valves serve critical functions in hazardous area applications including oil and gas pipelines, petrochemical plants, chemical processing facilities, and flammable liquid storage terminals.
Selection Considerations
Verify certification matches your specific hazardous area classification. Confirm CT6 rating is maintained at maximum ambient temperature. Select valve and actuator materials compatible with process media. Ensure proper power supply and control signal requirements are specified for reliable operation.
Summary
DN100 explosion proof electric gate valves with CT6 rating represent the highest safety level for hazardous area flow control. Selection requires careful evaluation of pressure rating, material, CT6 certification verification, and actuator requirements. Consulting with qualified manufacturers who provide full certification documentation ensures regulatory compliance and safe reliable operation.
