Flange connection, as one of the important connection methods in pipeline construction, originated from the Industrial Revolution at the end of the 18th century and was initially mainly used for cast iron low-pressure steam pipelines. With the development of technology and the rise of the petrochemical industry, the requirements for flanges are constantly increasing with the increasing demand, and international standards are also constantly improving and unifying with this process. Various connection methods such as welding, threading, clamps, etc. also appear in pipeline systems.

Butterfly valves play a vital role in water management systems due to their compact design, quick operation, and reliable sealing. KEFA Valve Group, with 60 years of expertise in water treatment, offers advanced butterfly valve solutions tailored for municipal water supply, wastewater treatment, seawater applications, and hydraulic engineering.

Butterfly valves are vital for pipeline flow control. Wafer-style designs offer installation flexibility in compact spaces, while lug-style ones provide stronger pressure resistance.

Butterfly valves are versatile flow-control devices widely used in industries such as water treatment, oil and gas, chemical processing, and HVAC systems.
