Other remarks 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. |
Other remarks 2 | SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing |
Other remarks 3 | Rising stem structure, making the valve switch position be clear at a glance |
Other remarks 4 | The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced. |
Other remarks 5 | Small switching moment, reliable sealing |
Other remarks 6 | The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good. |
Other remarks 7 | Small flow resistance, high flow capacity and good flow characteristics |
Other remarks 8 | For small gate valves, the interchangeability can be ensured with process tooling. |
Other remarks 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. |
