Technical characteristics

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.

The friction between sealing faces is smaller during opening and closing, facilitating a longer service life.

The valve clack is of taper, needle, ball and parabola types, and can be used to adjust the flow rate.

SS+ graphite or metallic seal 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.

A certain clearance is provided between valve clack and valve stem. You may adjust it by yourself. The sealing is reliable.

Short stroke is suitable for application at positions subject to frequent opening.
