Test standard | API 598、ISO 5208、JB/T9092、GB/T13927 |
Operation method | The valve clack is automatically opened and closed under the medium force. |
Application fields | Water, steam, petroleum, natural gas, etc. |
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 | Streamline flow pass, no bypass of medium, small valve flow resistance, and energy saving |
Other remarks 3 | Suitable for medium backflow prevention in pipeline or device |
Other remarks 4 | The floating valve clack structure is adopted to automatically compensate the error caused by wearing during installation and operation, to ensure the tight mating of sealing faces and improve the sealing performance. |
Other remarks 5 | Due to the short opening and closing travel and the automatic resetting without impact, the valve can be fully opened with a small flow rate, and the closing time can be short. |
