Threaded Plug Valve

Threaded plug valve refers to the connection method of plug valve, which is internal thread connection or external thread connection. Generally, there are more internal thread connections. The structure of threaded plug valve is relatively simple, mainly composed of valve body, plug and packing cover. The valve body has various forms such as straight through, three-way, and four-way. Straight through is used to cut off the medium, while three-way and four-way are used to change the direction of medium flow or distribute the medium. A plug is the opening and closing component of a plug valve, which is cylindrical or conical in shape, and its channel cross-section can be rectangular, trapezoidal, or circular. The threaded plug valve produced by Shanghai Meiyanyi Pump Valve adopts a metal to metal sealing structure, which has excellent sealing performance and basically no leakage. It has a wide range of flow regulation and can generally be used for controlling high flow and high pressure media.
