The GB Flange Butterfly Valve operates by rotating a disc within the valve body to control the flow of fluids. When the valve is opened, the disc rotates 90 degrees to allow the fluid to pass through with minimal resistance. When closed, the disc blocks the flow path, providing a tight seal that prevents leakage. The valve’s flanged connection ensures a secure, leak-proof installation, while its compact design ensures that it operates smoothly and efficiently in various applications.
