It features a high-toughness forged one-piece body structure that minimizes the risk of leakage.<\/p>\n<p>In addition, the main components are made from forged brass material. Compared to cast products, this significantly reduces the risk of cracking in threaded areas during piping installation.<\/p>\n<p>The valve body has a hexagonal shape and excellent machinability. Besides being suitable for various equipment and factory piping applications, its butterfly\/wing handle design enables installation even in extremely tight spaces or small equipment integration.<\/p>\n<ul>\n<li>Compact butterfly handle design, ideal for narrow-space piping.<\/li>\n<li>High-strength, seamless forged one-piece body (hot-forged) to minimize the risk of external leakage.<\/li>\n<li>Utilizes a floating ball valve structure.<\/li>\n<\/ul>\n<h5>What is a Floating Ball Valve Structure?<\/h5>\n<p>It supports the ball with PTFE seats that provide excellent sealing.
