Bidirectional Butterfly Valve

Bidirectional butterfly valve is separated from existing models to ensure the best performance in the two flow directions. This unique function provides a guarantee for unexpected reverse flow, thereby maximizing the life of the valve. It meets the various requirements made from various materials, from durable carbon steel to anti-resistant drug super alloy. The simplified design of the capable quarterly rotation system makes it suitable for high-end installation. The valve is enhanced through strong stems and three severe bearings, which can ensure the minimum torque and perfect characteristics. For accuracy and continuous performance, bidirectional butterfly valve is the best choice in the advanced flow control system.
