In industrial piping systems, globe valves—acting as core components integrating shut-off and regulation functions—directly determine the stability and economy of production processes through their sealing reliability and working condition adaptability. With years of dedication to fluid control, OUWEI manufactures high-quality globe valves to rigorous standards, becoming a trusted partner across industries including petroleum, chemical, power, and municipal engineering.
Adhering to the core principle of forced sealing, OUWEI globe valves achieve an ultra-low leakage rate of ≤0.01% (exceeding industry benchmarks) by driving the disc to tightly fit the seat via axial pressure from the valve stem. Catering to diverse operational needs, the product range covers full structural types (straight-through, angle, Y-type straight-flow) with nominal diameters from DN15 to DN1200 and pressure ratings from 1.6MPa to 42MPa. It adapts to extreme temperatures ranging from -196℃ (cryogenic) to 650℃ (high-temperature) and is compatible with various fluid transmission requirements, including water, steam, oil products, and corrosive media.
In core technology upgrades, OUWEI innovatively adopts Stellite cobalt-based cemented carbide overlay welding for sealing surfaces, combined with precision grinding processes—enhancing the wear resistance and scratch resistance of the sealing pair by over 3 times and extending stable operation life beyond 5000 hours. The bellows + packing double-sealing design completely eliminates stem leakage risks, making it ideal for flammable, explosive, toxic, and harmful medium scenarios. Valve bodies are crafted from high-quality materials such as 304/316 stainless steel and alloy steel, undergoing full-process digital control and liquid nitrogen cryogenic pretreatment to effectively prevent jamming and seal deformation caused by thermal expansion and contraction.
For actuation, OUWEI offers manual, electric, and pneumatic options. Electric models are equipped with low-torque precision actuators, enabling high-precision flow regulation of ±0.5% to adapt to automated control systems. Connection methods include three mainstream types (flange, thread, welding), strictly complying with international standards such as GB, API, and ANSI to ensure installation interchangeability and system compatibility. From chemical reactor feed control and power plant steam pipe shut-off to municipal water supply and drainage regulation and cryogenic liquefied medium transmission, OUWEI globe valves stand as a reliable safeguard for industrial production with core advantages of "precise control, stability, and long-term durability."
Backed by a dual support system of "technology + service," OUWEI provides full-cycle solutions: professional engineers tailor selection plans based on medium properties, pressure, temperature, and other operating parameters, while a nationwide service network ensures on-site installation, commissioning, and maintenance support within 48 hours. Choosing OUWEI globe valves means selecting not just a high-quality product, but a trusted guarantee for industrial fluid control.
