                  Other remarks 1 The valve seat is embedded with flexible seal ring for zero leakage of seal; 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 remarks 2 The pressure self-sealing is adopted between valve body and bonnet for reliable sealing, where the higher the pressure is, the better the sealing performance would be.
                  Other remarks 3 Rising stem structure, making the valve switch position be clear at a glance
                  Other remarks 4 The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced.
                  Other remarks 5 Small switching moment, reliable sealing
                  Other remarks 6 The self-sealing parallel double-plate and the stretching type parallel double-plate structures are adopted, so the sealing performance is good.
                  Other remarks 7 Small flow resistance, high flow capacity and good flow characteristics
                  Other remarks 8 Through improving the structural design and selecting reasonable packing structure and qualified packing supplier, the valves can meet the Class A sealing test requirements of ISO 15848 FE.
