Technical characteristics | 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 |
SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing. | |
Rising stem structure, making the valve switch position be clear at a glance. | |
The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced. | |
Small switching moment, reliable sealing | |
Small flow resistance, high flow capacity and good flow characteristics |
