lift check valve"},"content":{"rendered":"<p>Destandard lift check valve is widely used in nominal pressure PN16-PN40, working temperature -29~550\u2103 of petroleum, chemical, thermal power station and other working conditions of the pipeline, the applicable medium is: water, oil, steam and so on.<\/p>\n<p>&nbsp;<\/p>\n<p>Its main function is to prevent the backflow of the medium, to prevent the reverse of the pump and its drive motor, as well as the leakage of the medium in the container.<\/p>\n<p>Advantage<\/p>\n<p>1, the lifting check valve is an automatic sealing valve, the valve depends on the medium itself to flow and automatically open and close the valve disc, effectively prevent the backflow of the medium.<\/p>\n<p>&nbsp;<\/p>\n<p>2, the valve disc with stainless steel spring device, the valve can be .<\/p>\n<p>&nbsp;<\/p>\n<p>3, sealing surface wear resistance, corrosion resistance, friction resistance, long service life.<\/p>\n<p>&nbsp;<\/p>\n<p>4, the product structure is reasonable, reliable sealing, excellent performance, beautiful shape.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-183\"
