The globe valve is used to cut off the flow of the medium. The globe valve is suitable for frequently opened occasions. The sealing parts of the globe valve are the disc and the valve seat. In order to make the globe valve close tightly, the mating surface of the disc and the valve seat should be grinding or using gaskets. The sealing surface can also be inset with bronze, stainless steel and other corrosion-resistant and wear-resistant materials. The disc and stem of the globe valve are connected with each other, so that the disc and stem are closely fitted. The lifting of the disc of the globe valve is generally controlled by the stem. The upper part of the stem of the globe valve is the handwheel, and the middle part is the thread and packing sealing section. The role of the packing is to prevent the internal medium of the valve body from leaking along the stem.
