Other remarks 1 | The extension dimensions of valve stem and bonnet may vary according to different temperature ratings. |
Other remarks 2 | As valves subject to a temperature ≤-101℃ shall be protected against subzero deformation, the main parts are subzero treated. |
Other remarks 3 | 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 4 | The friction between sealing faces is smaller during opening and closing, facilitating a longer service life. |
Other remarks 5 | The valve clack is of taper, needle, ball and parabola types, and can be used to adjust the flow rate. |
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 | Rising stem structure, making the valve switch position be clear at a glance |
Other remarks 8 | The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced. |
Other remarks 9 | Small switching moment, reliable sealing |
Other remarks 10 | The valve clack can be machined into parabola, spherical, needle shapes, etc. according to the requirement of customer. It can be used for adjustment (rough adjustment) on pipeline. |
Other remarks 11 | Short stroke is suitable for application at positions subject to frequent opening. |
Other remarks 12 | Y-shape stop valve – the streamline flow pass has a very high flow coefficient, and can maximally reduce the pressure drop through the system. |
Other remarks 13 | 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. |
