The ductile iron concentric flanged resilient seated butterfly valve is a high-performance valve designed for reliable and efficient flow control in various industrial applications. It offers a cost-effective solution with excellent durability, long service life, and low maintenance requirements.

Components of concentric flanged resilient seated butterfly valve and their material options:

the ductile iron concentric flanged resilient seated butterfly valve mainly consists of the valve body, valve plate, valve shaft, valve seat, operator(hand lever, hand wheel, actuators).

The valve body and plate of concentric flanged resilient seated butterfly valve are made of high-quality ductile iron, known for its strength and corrosion resistance. The valve seat of concentric flanged resilient seated butterfly valve, typically made of EPDM or NBR rubber, or PTFE, ensures a tight seal and provides resistance to wear and chemicals. The shaft of concentric flanged resilient seated butterfly valve, often made of stainless steel, connects the actuator and disc, allowing for smooth operation and precise control.

Additionally, the concentric flanged design features bolt holes around the valve’s circumference, providing secure and easy installation. The flange material can be customized to suit specific project requirements, commonly made of carbon steel or stainless steel.

Working principle of ductile iron concentric flanged resilient seated butterfly valve:

The working principle of the ductile iron concentric flanged resilient seated butterfly valve revolves around the rotation of the valve plate, controlled by the hand lever, hand wheel or actuators. When the concentric flanged resilient seated butterfly valve is in the closed position, the plate seals against the valve seat, preventing any leakage. As the actuator rotates, the valve plate opens, allowing the fluid or gas to flow through the concentric flanged butterfly valve. The precision engineering of the concentric flanged resilient seated butterfly valve ensures a tight seal even under high-pressure conditions.
