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
