The flange butterfly valve has a sturdy design and low maintenance requirements, providing an economical valve solution for precise and durable medium flow in industrial pipelines to improve pipeline efficiency, reduce operating costs, and protect system safety. Flange butterfly valves offer a variety of sizes and flange types to adapt to pipeline systems in different regions. Pneumatic and electric actuators can achieve more precise flow control.
The flange butterfly valve is connected to the pipeline flange and actuator through ductile iron flange butterfly valve body / carbon steel flange butterfly valve body / stainless steel flange butterfly valve body, ensuring the safe and stable operation of the pipeline route.
We offer flanged butterfly valves with various flange standards and materials to ensure efficient fluid control, and can provide customized solutions to meet specific operating conditions.
● Face-to-face length according to EN 558 series 13.
● It can be rubber-lined (vulcanized) for seawater and polluted media applications.
● Epoxy coating internally and externally, Halar coating, and conventional and special conditions of C1-C5 & CX
