1. The valve adopts a straight-through structure.

2. In order to avoid the medium's high-speed scouring of the sealing pair during use, the sealing degree adopts a double valve seat structure, first throttling and blocking the stolen goods, and using the throttling medium to make the sealing surface self-clean, thus completely solving When the valve is closed, because the dirty medium is pressed on the sealing surface of the valve seat, the valve will have the problems of leakage and short service life.

3. The connection between the body and the bonnet of the anti-scouring globe valve with a nominal diameter of DN≤50mm is a clamp pin shaft connection, and the connection between the body and the bonnet of the anti-scouring globe valve above DN65 is a self-sealing flange connection. form. Both of these two structures are easy to disassemble, assemble, safe and reliable.

4. The branch pipes at both ends of the valve are connected by welding.

5. The valve seat and valve disc sealing surface are made of imported cobalt-based hard alloy surfacing. The sealing surface has the characteristics of high hardness, abrasion resistance and abrasion resistance.

6. Nitrided steel is used as the stem material to make the surface of the stem after nitriding have high hardness, wear resistance, scratch resistance, corrosion resistance and long service life.
