In high-risk industries such as oil and gas extraction, petroleum refining, chemical processing, long-distance pipelines, and liquefied natural gas (LNG) terminals, safety is always the core red line that overrides all economic benefits. Because the media transported through the pipelines are mostly flammable, explosive, and volatile oils and natural gases, the production sites permanently harbor explosive gas and dust mixtures. Under such harsh working conditions, any tiny electrical spark within the automation control system could trigger catastrophic and irreversible consequences. Therefore, explosion-proof automation control equipment with extremely high safety ratings has become an inevitable choice for oil and gas storage and transportation networks.The main stop valve product names of China Stop Valve Network include:Electric Flange Straight-through Globe Valve, Electric Cast Steel Self-sealing Tightly Globe Valve, High Temperature and Pressure Power Station Electric Globe Valve, Forged SteelStraight-through Globe Valve, Liquefied Gas Globe Valve, Flange Straight-through Low Temperature Globe Valve, Self-sealing Straight-through Globe Valve, Y-type Butt Welded Globe Valve.

As a professional explosion-proof electric globe valve manufacturer for oil & gas dedicated to high-end fluid control equipment manufacturing, we deeply understand the industry's ultimate demands for safety. To this end, we have meticulously developed a serialized lineup of intelligent electric globe valves certified under the European Union's ATEX explosion-proof directive. From electrical design and mechanical structure to material selection and fabrication, our products construct a comprehensive and rigorous explosion-proof fluid safety barrier, aiming to provide non-compromising safe flow control solutions for global petrochemical plants, long-distance pipelines, and flammable media handling systems.

Core Processes & Key Advantages

• Authoritative ATEX Explosion-Proof Certification: The electric actuators paired with our valves are strictly engineered in accordance with the latest EU explosion-proof directives and have proudly obtained ATEX certification. The flameproof (Ex d) enclosure can withstand internal explosion pressures without damage and prevents internal flames from propagating to the explosive mixtures surrounding the housing—perfectly matching extremely hazardous oil and gas zones like Zone 1 and Zone 2.

• Robust, Wear-Resistant Structure for Oil & Gas: The valve body is forged or precision-cast from premium carbon steel (WCB), low-temperature steel (LCB), or high-strength stainless steel (CF8M), delivering exceptional pressure-bearing capabilities and resistance to chemical stress corrosion. The sealing faces of the valve disc and seat are overlaid with Stellite hard alloy, resisting oil erosion and impurity wear to ensure absolute zero-leakage during frequent opening and closing cycles.

• Highly Reliable & Intelligent Control: Integrated with a digital, intelligent all-in-one control module, the valve supports non-intrusive infrared configuration and fieldbus control (Modbus/Profibus). The system features built-in over-torque protection, valve jam alarms, and power/signal-loss self-locking or fail-safe reset functions, allowing it to shut down or open pipelines rapidly and reliably during emergencies.

As a source factory possessing both the national special equipment manufacturing license (TS Certification) and dual international explosion-proof credentials, we are equipped with cutting-edge CNC machining centers, explosion-proof electrical performance laboratories, and high-pressure gas-tight sealing test rigs. We can provide you with complete technical solutions for specialized oil and gas electric globe valves ranging from low to high pressure, and ambient to cryogenic temperatures, tailored to your diverse oil and gas pipeline conditions. Choosing our ATEX explosion-proof electric globe valves means installing an indestructible "safety firewall" for your high-risk production sites.
