Forged steel valves are manufactured using forging technology and are renowned for their high strength, resistance to high temperatures and pressures, and impact resistance. Their core components, such as the valve body and cover, are made of carbon steel, stainless steel, or alloy steel through high-temperature forging, eliminating casting defects such as porosity and sand holes. Nominal pressures can reach 4500LB (76.0MPa). Their unique self-sealing design ensures increasingly reliable sealing at higher pressures, making them suitable for controlling the opening and closing of fluids such as steam, water, oil, and corrosive media.

Valves are crucial control components in fluid transport systems, playing an indispensable role in our daily lives, industrial production, oil transportation, and more. Although a valve is just a small component, its function is extremely important.It can perform opening and closing functions, cutting off or connecting the flow of fluid media by fully opening or closing, isolating equipment and pipeline systems; it has a regulating function, adjusting pipeline resistance by changing the valve opening, thereby regulating the fluid’s velocity, pressure, and flow rate; it can control the flow direction, such as check valves preventing fluid backflow, and distribution valves distributing and controlling the flow direction of fluid; it also has a safety protection function, when the pressure in the pipeline or equipment exceeds the specified value, safety valves will automatically release pressure to maintain a certain level and ensure safety.

The double offset butterfly valve achieves a “double eccentric” structure by simultaneously offsetting the valve stem axis from both the butterfly plate center and the valve body center. Compared to center-line butterfly valves, it offers greater pressure resistance, stability, and service life; it also supports metal seats and can operate at temperatures up to 500°C, extending its application to high-temperature conditions. The valve has lower flow resistance, making it particularly suitable for large-diameter water, gas, oil, and corrosive media pipelines (DN200 and above) for regulation or shut-off applications.
