The disc swings open with forward flow and closes automatically under gravity and reverse flow, protecting pumps and equipment from backflow. Its full-bore flow path gives low pressure loss, and the cover can be removed for inspection without taking the valve out of the line.<\/p>\n<h5><strong>\u6280\u672f\u89c4\u683c\uff1a<\/strong><\/h5>\n<ul>\n<li><strong>\u538b\u529b\u7b49\u7ea7\uff1a<\/strong> PN10 \/ PN16<\/li>\n<li><strong>\u5c3a\u5bf8\u8303\u56f4\uff1a<\/strong> DN50 \u2013 DN600<\/li>\n<li><strong>\u9002\u7528\u4ecb\u8d28\uff1a<\/strong> Water, sewage, oil, steam<\/li>\n<li><strong>\u5de5\u4f5c\u6e29\u5ea6\uff1a<\/strong> -10\u00b0C to 200\u00b0C (metal seat) \/ 80\u00b0C (rubber seat)<\/li>\n<\/ul>\n<h5><strong>Main Parts and Materials:<\/strong><\/h5>\n<table cellspacing=\"0\">\n<tbody>\n<tr>\n<td><strong>\u90e8\u4ef6\u540d\u79f0<\/strong><\/td>\n<td><strong>\u6750\u6599<\/strong><\/td>\n<\/tr>\n<tr>\n<td>\u9600\u4f53\u3001\u9600\u76d6<\/td>\n<td>\u7070\u94f8\u94c1HT200 \/ \u7403\u58a8\u94f8\u94c1QT450<\/td>\n<\/tr>\n<tr>\n<td>\u9600\u74e3<\/td>\n<td>Cast Iron \/ Ductile Iron<\/td>\n<\/tr>\n<tr>\n<td>\u9600\u5ea7\u73af<\/td>\n<td>Brass \/ EPDM<\/td>\n<\/tr>\n<tr>\n<td>\u6447\u81c2\u9500\u8f74<\/td>\n<td>\u4e0d\u9508\u94a22Cr13<\/td>\n<\/tr>\n<tr>\n<td>\u57ab\u7247<\/td>\n<td>NBR\/\u77f3\u58a8<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h5><strong>\u4ea7\u54c1\u4e3b\u8981\u7279\u70b9\uff1a<\/strong><\/h5>\n<ol>\n<li><strong>\u81ea\u52a8\u5de5\u4f5c\uff1a<\/strong> No external power or control needed to prevent backflow.<\/li>\n<li><strong>Low Head Loss:<\/strong> Disc swings fully clear of the flow path when open.<\/li>\n<li><strong>Reliable Seating:<\/strong> Copper or rubber seat rings for tight closure.<\/li>\n<li><strong>\u9876\u90e8\u68c0\u4fee\uff1a<\/strong> Bolted cover for in-line inspection and disc maintenance.<\/li>\n<li><strong>\u5b89\u88c5\u7075\u6d3b\uff1a<\/strong> \u6c34\u5e73\u6216\u5782\u76f4\uff08\u5411\u4e0a\u6d41\u52a8\uff09\u7ba1\u7ebf\u3002<\/li>\n<\/ol>\n<h5><strong>\u5e94\u7528\uff1a<\/strong><\/h5>\n<p>\u9002\u7528\u4e8e <strong>\u6c34\u6cf5\u51fa\u6c34\u7ba1<\/strong>, <strong>\u4f9b\u6c34<\/strong>, <strong>Drainage &amp; Sewage<\/strong>\u4ee5\u53ca <strong>\u4f9b\u6696\u7cfb\u7edf<\/strong>.
