Centerline Wafer Butterfly Valve

Let's clarify the parameters first so you can have a clear idea: the diameter ranges from DN40 to DN1600, which can be used for everything from small pipe branches to large main pipelines; it can withstand pressures from PN1.0 to PN2.5MPa, meeting the pressure requirements of general chemical and municipal applications; the temperature range is -10℃ to 200℃, allowing normal operation for both room-temperature clean water and slightly high-temperature oil products. In terms of materials, the valve body can be cast iron or cast steel, and the sealing surface is made of EPDM rubber, which is wear-resistant and anti-aging. The connection method is flange, complying with the GB/T 12238 standard. It can be directly connected and installed on-site without additional processing, saving working hours and reducing errors.

Anyone who has used butterfly valves knows that some valves are either hard to open/close or leak after long-term use-but our center-line butterfly valve avoids these issues. Its butterfly plate and valve stem are integrally formed, with no loose gaps, making opening and closing extremely smooth. Manual operation requires no great effort, and if you choose the electric version, the opening/closing response takes only about 1 second, enabling precise flow regulation. Additionally, the center-line design ensures that the butterfly plate and sealing surface are always in uniform contact; even with frequent opening and closing, the sealing effect remains strong, with a leakage rate lower than the national standard requirement. Maintenance is also simple-just wipe the sealing surface regularly, no need for disassembly and overhauls, saving a lot of maintenance costs.

As for its applications, the range is very wide. It can be used for municipal water supply pipe network regulation, residential heating water circulation control, and chemical plant solvent transportation. For scenarios requiring high-low pressure coordination, such as the refined oil transportation pipeline in an oil refinery, floating ball valves can be used at the front end for high-pressure shut-off, and center-line butterfly valves at the back end for precise flow regulation. Their cooperation ensures both safety and efficiency. In sewage treatment plants, center-line butterfly valves can regulate inlet flow, paired with floating ball valves to control sludge discharge, making the entire process highly stable.
