In harsh industrial scenarios with high pressure and high temperature such as petrochemical, metallurgical and electric power industries, the material and performance of control valves directly determine the stability and safety of the system. The carbon steel series control valves of the OUWEI brand, with high-strength materials and precise control technology, have become a hard-core guarantee for industrial fluid control.
OUWEI carbon steel control valves adopt high-quality WCB carbon steel for the valve body, which can withstand a wide temperature working environment of -20℃~425℃, with nominal pressure covering 1.6MPa~6.4MPa and compatible with DN25~DN300 multi-specification flange connections, and can easily handle the precise flow control of steam, heat transfer oil and various process media. Its built-in high-precision electric/pneumatic actuator supports 0.5-level adjustment accuracy, and with the equal percentage flow characteristic valve core, it can achieve linear flow matching under working conditions; the carbon steel valve body has undergone integral forging and non-destructive testing, with excellent impact and corrosion resistance, and adopts a double sealing structure of hard seal + soft seal. The leakage rate meets the ANSI B16.104 Class VI standard, and can maintain stable shut-off even under complex working conditions with high pressure difference and strong medium.
With a complete quality control system, OUWEI carbon steel control valves have passed a number of industrial certifications and are widely used in core processes such as refining and chemical units, power station auxiliary control, and metallurgical blast furnaces. With professional technical solutions and reliable product quality, they have built a solid fluid control line of defense for industrial production, interpreting the strict standards and technical pursuit of OUWEI brand for industrial-grade valves.
