Application fields | For application in fields such as electric power industry, petroleum refining, petrochemical engineering, offshore oil, tap water engineering in urban construction, chemical engineering, etc. |
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. |
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 | |
The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good. | |
Small flow resistance, high flow capacity and good flow characteristics | |
For small gate valves, the interchangeability can be ensured with process tooling. | |
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. |
