Electric Welding Globe Valve

Our Electric Welding Globe Valve is a high-performance industrial control valve that combines an electric actuator with a butt weld connection, designed for precise on/off control and flow regulation in harsh industrial environments. It integrates advanced structural design and high-quality materials, ensuring reliable sealing, strong pressure resistance, and easy automated operation, making it an ideal choice for pipelines requiring high tightness and remote control in industries such as oil & gas, petrochemical, power generation, and water treatment.
Unlike flange-connected valves, the butt weld design eliminates potential leakage points, providing superior sealing performance and structural integrity, which is especially suitable for high-pressure, high-temperature, or corrosive medium transmission systems. The electric actuator converts electrical signals (4-20mA or switch signals) into linear motion of the valve disc, enabling accurate flow adjustment and real-time position feedback, supporting remote control through DCS/PLC systems for efficient industrial automation management.

1.Superior Leak-Proof Performance : The valve body and bonnet adopt an integral welding structure, eliminating bolt gaps and potential leakage risks, achieving zero leakage even in high-pressure and high-temperature working conditions. The valve seat uses PTFE, PPL, or metal composite sealing materials, with strong adaptability to pressure and temperature changes, ensuring long-term reliable sealing.

2.High Pressure & Temperature Resistance : The valve body is manufactured by forging process, which ensures high material density and excellent mechanical strength, capable of withstanding working pressure up to PN42.0MPa and working temperature ranging from -40℃ to 570℃, suitable for harsh working conditions such as steam pipelines and high-pressure chemical media transmission.

3.Precise Electric Control : Equipped with a high-precision electric actuator, it supports both on/off control and modulating control (4-20mA signal), with accurate flow regulation and fast response speed. It has built-in torque overload protection, overheat protection, and electrical protection functions, and can be equipped with a manual emergency device for manual operation in case of power failure.

4.Durable & Corrosion-Resistant : Valve body materials include carbon steel, stainless steel (SS304, SS316), and alloy steel, which can be customized according to the medium characteristics. The valve stem is made of integral forging process with precision grinding, and the surface is treated with anti-corrosion technology, reducing wear and corrosion points and extending the service life of the valve.

5.Easy Installation & Low Maintenance : The butt weld connection is directly welded to the pipeline, ensuring high connection strength and reducing installation space. The boltless structure reduces maintenance difficulty; the sealing ring is removable and easy to replace, and the valve is designed with a valve stem anti-flying structure and anti-static device, ensuring safe and stable operation.

6.Compliance with International Standards : Strictly manufactured in accordance with API 6D, API 600, GB12237, and other international and national standards, with complete inspection and testing procedures, meeting the quality requirements of global industrial markets and passing ISO, CE, and other certifications (optional).

- Oil & Gas Industry : Oil extraction, natural gas transmission, refineries, and long-distance pipeline systems, especially suitable for harsh working conditions such as sulfur-containing media and high-pressure transmission.

- Petrochemical Industry : Chemical reaction pipelines, corrosive medium transmission, and high-temperature and high-pressure process pipelines, ensuring safe and stable operation of the production process.

- Power Generation Industry : Thermal power plants, nuclear power plants, boiler feed water, steam systems, and cooling water pipelines, meeting the high-precision control requirements of power generation equipment.

- Water Treatment & Municipal Engineering : Large-diameter water supply and drainage pipelines, sewage treatment systems, and heating pipelines, with long service life and low maintenance costs.

- Metallurgy & Mining Industry : Smelting process pipelines, mineral processing fluid control, and high-temperature flue gas treatment pipelines, adapting to harsh working environments such as high temperature and dust.

- Pharmaceutical & Food Industry : Clean pipeline systems, medium transmission for pharmaceutical and food processing, with food-grade materials optional to ensure product safety (optional customization).
