26.ATEX Certified Explosion-Proof Electric Globe Valve Manufacturers for Oil & Gas
Any electrical equipment used in these zones must be engineered to prevent ignition, making ATEX-certified explosion-proof valves an absolute safety requirement rather than an optional upgrade. The ATEX-certified explosion-proof electric globe valve has become the standard for reliable flow control in these high-risk applications, and selecting the right manufacturer is critical for operational safety and regulatory compliance.The main globe valve product names of China globe Valve Network include:GB Cast Steel Flange Globe Valve,GB Stainless Steel Flange Globe Valve,GB Bellows Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,Insulation Globe Valve,Inner Thread Straight-through Stainless Steel Globe Valve,Internal Thread Ammonia Globe Valve,Liquefied Gas Globe Valve.

Understanding ATEX Certification for Oil and Gas Service
ATEX is the European Union's mandatory directive (2014/34/EU) governing equipment intended for use in potentially explosive atmospheres. For oil and gas applications, ATEX certification ensures that the valve and its actuator are designed to prevent ignition of surrounding flammable gases.
The most common ATEX marking for explosion-proof globe valves is Ex d IIC T6 Gb or Ex d IIC T5 Gb. The Ex d designation indicates a flameproof enclosure—the housing can withstand an internal explosion without transmitting it to the surrounding atmosphere. The IIC gas group covers the most hazardous gases, including hydrogen and acetylene. The T6 temperature class ensures the surface temperature remains below 85°C, significantly lower than the auto-ignition temperature of most hydrocarbons.
The ATEX certification applies to both Zone 1 (explosive atmosphere likely during normal operation) and Zone 2 (explosive atmosphere not likely, or only for short periods) hazardous areas.
Stellite hardfacing on the valve disc and seat sealing surfaces resists oil erosion and impurity wear, ensuring absolute zero-leakage during frequent opening and closing cycles. This is particularly important in oil and gas service where media often contains abrasive particulates.
Intelligent control integration enables seamless connection to plant automation systems. ATEX-certified actuators support on/off control via dry contacts, or modulating control via 4-20mA signals, with position feedback for DCS/PLC integration. Advanced models feature built-in over-torque protection, valve jam alarms, and fail-safe reset functions.
Key Manufacturers and Suppliers
Several manufacturers offer ATEX-certified explosion-proof globe valves suitable for oil and gas service. The following are notable suppliers with demonstrated capabilities in this specialized field.
Valve Body and Trim Materials – Select materials compatible with the specific oil and gas media. Carbon steel (WCB) is standard for non-corrosive hydrocarbons. Low-temperature steel (LCB) is required for cryogenic service. Stainless steel (CF8M) is specified for sour service or corrosive media. Stellite hardfacing on sealing surfaces is strongly recommended for wear resistance.
Pressure and Temperature Ratings – Confirm the valve's pressure rating matches the pipeline's maximum operating pressure. Standard ratings for oil and gas globe valves are PN16 to PN160 (Class 150 to Class 900), with temperatures ranging from -29°C to 550°C.
Control Mode – Determine whether on/off (switching) control or modulating (proportional) control is required. For modulating control, specify an actuator with a positioner accepting 4-20mA input signals. Intelligent actuators with fieldbus communication (Modbus/Profibus) offer advanced diagnostics and remote configuration.
Ingress Protection – Specify a minimum of IP67 for the actuator enclosure to ensure protection against dust and water ingress. IP68 is available for outdoor or washdown environments.
The ATEX-certified explosion-proof electric globe valve is a critical safety component for oil and gas flow control, offering reliable remote operation in the most hazardous environments. Qualified manufacturers such as VINCER, DELCO, BEL Valves, and specialized Chinese producers provide ATEX-certified solutions with flameproof actuators, appropriate material selections, and integrated control features. When selecting this valve for oil and gas service, pay careful attention to the ATEX certification scope (verify Ex d IIC T6/T5), body and trim material compatibility, pressure rating, control mode, and ingress protection. Investing in a correctly specified ATEX-certified globe valve is not merely a purchase—it is an investment in operational safety, regulatory compliance, and the long-term reliability of your oil and gas processing systems.
