1. Y-type straight-through structure, small flow resistance, left and right valve body separated, between the two valve bodies with a seat, maintenance only need to remove the bolts of the two valve bodies can be cleaned or repaired, if there are damaged parts can be replaced in time.

2. When opening the valve, the valve body can be protected from erosion and corrosion by the medium, thus greatly improving the service life of the valve, overlaying between the sealing surfaces with hard alloy, high hardness.

3. The valve disc adopts conical sealing surface, and the valve seat adopts a tiny circular arc cover. In this way, when the disc and the valve seat close together form a similar line seal form, sealing effect is very good.

4. The valve has an upper sealing structure, which can protect the packing when it is fully opened. The valve guiding device is arranged outside the body cavity and does not contact with the medium, thus preventing the jamming of the guiding part similar to the gate valve.
