              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
