Other remark 1 | the valve seat and the slide sealing surface are build-up welded with hard alloy to improve the scouring resistance and extend the service life of the valve |
Other remark 2 | SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing. |
Other remark 3 | Rising stem structure, making the valve switch position be clear at a glance. |
Other remark 4 | The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced. |
Other remark 5 | Small switching moment, reliable sealing |
Other remark 6 | Small flow resistance, high flow capacity and good flow characteristics |
