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.
