Product features

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.

2.SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing

3.Rising stem structure, making the valve switch position be clear at a glance

4.The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced.

5.Small switching moment, reliable sealing

6.The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good.

7.Small flow resistance, high flow capacity and good flow characteristics

8.For small gate valves, the interchangeability can be ensured with process tooling.

9.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.
