Threaded Butterfly Valve

A threaded butterfly valve is a manually operated valve that is designed to open and close a pipeline by using a circular disk inserted in the center of the valve. The disk is rotated using a threaded shaft in the middle of the valve, which allows it to be regulated to open, close and partially adjust the flow of liquid, gas or other materials through it. Threaded butterfly valves are often used for applications where temperature and pressure needs to be regulated, and are recommended for low-pressure and low-temperature systems.
