Product Overview<\/h4>\n<div class=\"auto-hide-last-sibling-br paragraph-jgxDqs paragraph-element br-paragraph-space\">VALVEFAC DN80 hydraulic vertical check valves are constructed from WCB carbon steel, designed to GB\/T 12235 and API 594 standards. The valve disc lifts along vertical guide rods to prevent backflow automatically. With a nominal diameter of DN80 (3\u2033) and pressure classes PN16-PN160 (150LB-1500LB), it operates at -10\u2103~80\u2103, specialized for water pipelines in municipal water supply, industrial circulating water, and building fire protection.<\/div>\n<h4 class=\"header-ZWWO7s auto-hide-last-sibling-br\">II.
