    Reasonable price Acs Butterfly Valve - PTFE lined butterfly valve – Nortech

    Product Detail: What is PTFE lined butterfly valve ? PTFE lined butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc...
