These valves operate on a simple yet effective principle: a barrier (gate) moves perpendicular to the flow path, either allowing full flow or completely stopping it. Understanding how gate valves function is essential for engineers, technicians, and anyone involved in system design or maintenance.<\/p>\n<div class=\"img-container\">\n<div class=\"image-embed\"
