It is mounted properly in the valve body cavity to isolate the body from contacting the fluid. The polyurethane liner has\u00a0<strong>excellent abrasion resistance<\/strong>\u00a0et\u00a0<strong>wear resistance<\/strong>, as well as good corrosion resistance to a wide range of chemicals. This makes it ideal for applications where there is a high level of abrasion and\/or corrosion present, and where reliable and long-lasting performance is required.<\/li>\n<li><strong>Two-piece body design<\/strong>: The MP-series PU knife gate valve is constructed by two separate half valve bodies that are bolted together. The two half bodies compact the polyurethane liner firmly within the body cavity, properly aligned and centered. This construction allows for easier maintenance and repair.<\/li>\n<li><strong>Resilient seat &amp; bidirectional flow<\/strong>: It resembles the\u00a0MR-series. A resilient U-type seat ring is fitted in the preformed groove of the polyurethane liner. When the disc is moving down or up, the resilient seat is compacted into the groove or bouncing back to be level with the groove. No residual fluid will be retained by the body cavity and self-cleaning of the flow passage is achieved. The possibility of clogging will be reduced. Due to its resilient seated design, bidirectional installation is applicable providing greater flexibility and versatility for flow control.<\/li>\n<li><strong>Disc scrapers<\/strong>: A pair of scrapers will be furnished to remove the slurries or solid particulates from the disc, ensuring good sealing performance and smooth on-off operation of the valve.<\/li>\n<\/ul>\n<h2>Material Selection<\/h2>\n<p>&nbsp;<\/p>\n<table id=\"tablepress-1013\" class=\"tablepress tablepress-id-1013\" style=\"height: 646px;\" width=\"945\">\n<thead>\n<tr class=\"row-1\">\n<th class=\"column-1\">Part No.<\/th>\n<th class=\"column-2\">Nom de la pi\u00e8ce<\/th>\n<th class=\"column-3\">Material Grade<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-hover\">\n<tr class=\"row-2\">\n<td class=\"column-1\">1<\/td>\n<td class=\"column-2\">Volant<\/td>\n<td class=\"column-3\">GGG40, WCB<\/td>\n<\/tr>\n<tr class=\"row-3\">\n<td class=\"column-1\">2<\/td>\n<td class=\"column-2\">Bearing<\/td>\n<td class=\"column-3\">ZChSnSb10-6<\/td>\n<\/tr>\n<tr class=\"row-4\">\n<td class=\"column-1\">3<\/td>\n<td class=\"column-2\">Yoke Head<\/td>\n<td class=\"column-3\">GGG40, WCB<\/td>\n<\/tr>\n<tr class=\"row-5\">\n<td class=\"column-1\">4<\/td>\n<td class=\"column-2\">Joug<\/td>\n<td class=\"column-3\">Mild Steel<br \/>\nSS304<\/td>\n<\/tr>\n<tr class=\"row-6\">\n<td class=\"column-1\">5<\/td>\n<td class=\"column-2\">Tige<\/td>\n<td class=\"column-3\">2Cr13, SS410<br \/>\nSS304, SS316<\/td>\n<\/tr>\n<tr class=\"row-7\">\n<td class=\"column-1\">6<\/td>\n<td class=\"column-2\">Bolt &amp; Nut<br \/>\n(for Gland)<\/td>\n<td class=\"column-3\">SS201\/ SS304<\/td>\n<\/tr>\n<tr class=\"row-8\">\n<td class=\"column-1\">7<\/td>\n<td class=\"column-2\">Emballage<\/td>\n<td class=\"column-3\">PTFE, NBR<\/td>\n<\/tr>\n<tr class=\"row-9\">\n<td class=\"column-1\">8<\/td>\n<td class=\"column-2\">Disque<\/td>\n<td class=\"column-3\">SS304, SS304L<br \/>\nSS316, SS316L<br \/>\nDuplex 2205<br \/>\nA182 F53, F55<\/td>\n<\/tr>\n<tr class=\"row-10\">\n<td class=\"column-1\">9<\/td>\n<td class=\"column-2\">Scraper<\/td>\n<td class=\"column-3\">PTFE<\/td>\n<\/tr>\n<tr class=\"row-11\">\n<td class=\"column-1\">10<\/td>\n<td class=\"column-2\">Seat Liner<\/td>\n<td class=\"column-3\">Polyurethane<\/td>\n<\/tr>\n<tr class=\"row-12\">\n<td class=\"column-1\">11<\/td>\n<td class=\"column-2\">Body Nuts<\/td>\n<td class=\"column-3\">SS201\/ SS304<\/td>\n<\/tr>\n<tr class=\"row-13\">\n<td class=\"column-1\">12<\/td>\n<td class=\"column-2\">U-type Seat<\/td>\n<td class=\"column-3\">EPDM, NBR<\/td>\n<\/tr>\n<tr class=\"row-14\">\n<td class=\"column-1\">13<\/td>\n<td class=\"column-2\">Body Bolt<\/td>\n<td class=\"column-3\">SS201\/ SS304<\/td>\n<\/tr>\n<tr class=\"row-15\">\n<td class=\"column-1\">14<\/td>\n<td class=\"column-2\">Corps<\/td>\n<td class=\"column-3\">GGG40, WCB<br \/>\nCF8, CF8M<br \/>\nCF3, CF3M<br \/>\nDuplex 2205<\/td>\n<\/tr>\n<tr class=\"row-16\">\n<td class=\"column-1\">15<\/td>\n<td class=\"column-2\">Packing Gland<\/td>\n<td class=\"column-3\">GGG40, WCB<br \/>\nCF8, CF8M<br \/>\nCF3, CF3M<\/td>\n<\/tr>\n<tr class=\"row-17\">\n<td class=\"column-1\">16<\/td>\n<td class=\"column-2\">Bolt &amp; Nut<br \/>\n(for Yokes)<\/td>\n<td class=\"column-3\">SS201\/ SS304<\/td>\n<\/tr>\n<tr class=\"row-18\">\n<td class=\"column-1\">17<\/td>\n<td class=\"column-2\">\u00c9crou de tige<\/td>\n<td class=\"column-3\">Laiton<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>*Available sizes from DN50 to DN800.
