|
Other remarks 1 |
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. |
|
Other remarks 2 |
The gate valve is of wedge and resilient type that can compensate the slight deformation, so the sealing performance is good. |
|
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 |
SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing |
|
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 |
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. |
Design of Disc
Gate valves with NPS>=2 are flexible gate,gate valves with with NPS<2 are of solid gate.
If being requested by the customer,the Belleville spring loaded packing impacting system can be adopted for enhancing the durability and reliability of the packing seal.
