rel=\"noopener\">v\u00e1lvula de compuerta de acero fundido<\/a> is a linear motion valve that uses a gate or wedge-shaped disc that moves perpendicular to the flow path to control fluid passage. The term &#8220;cast steel&#8221; refers to the manufacturing process where molten steel (typically ASTM A216 WCB carbon steel) is poured into molds to create the valve body and components.<\/p>\n<p>This construction method provides exceptional strength, pressure containment, and temperature resistance compared to cast iron or bronze alternatives. Cast steel gate valves excel in applications requiring robust performance under extreme conditions, including high pressure, temperature fluctuations, and demanding industrial environments.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Operating_Principle\"><\/span>Operating Principle<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Gate valves operate on a simple principle: a wedge-shaped disc (the &#8220;gate&#8221;) moves perpendicular to the flow path. When fully open, the gate is completely removed from the flow path, creating minimal pressure drop and allowing full, unobstructed flow. When closed, the wedge seats firmly against both sides of the valve body, creating a tight seal.<\/p>\n<div class=\"two-columns\">\n<div>\n<h4><span class=\"ez-toc-section\" id=\"Rising_Stem_Design\"><\/span>Rising Stem Design<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>In rising stem configurations, the stem is attached to the gate and rises out of the valve as it opens. This provides a visual indication of valve position but requires more vertical clearance.<\/p>\n<\/div>\n<div>\n<h4><span class=\"ez-toc-section\" id=\"Non-Rising_Stem_Design\"><\/span>Non-Rising Stem Design<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Non-rising stem designs have threads inside the gate.
