| Other remarks 1 | The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve. |
| Other remarks 2 | The friction between sealing faces is smaller during opening and closing, facilitating a longer service life. |
| Other remarks 3 | The valve clack is of taper, needle, ball and parabola types, and can be used to adjust the flow rate. |
| Other remarks 4 | SS+ graphite or metallic seal is adopted between valve body and bonnet for reliable sealing. |
| Other remarks 5 | Rising stem structure, making the valve switch position be clear at a glance |
| Other remarks 6 | The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced. |
| Other remarks 7 | A certain clearance is provided between valve clack and valve stem. You may adjust it by yourself. The sealing is reliable. |
| Other remarks 8 | Short stroke is suitable for application at positions subject to frequent opening. |
