The ball surface can be treated<br \/>\nwith supersonic tungsten carbide spraying or carbonyl-process thermal spraying<br \/>\nwith nickel-based nano powder. This treatment can increase the surface hardness<br \/>\nof the ball to above 60 HRC.<\/p>\n<p>The valve seat is manufactured from hard materials or hard alloy overlay. This<br \/>\nenables the valve to withstand wear, particle erosion and high-velocity media<br \/>\nduring opening and closing. Flexible graphite packing and stainless steel<br \/>\nflexible graphite spiral-wound gaskets allow the valve to operate reliably under<br \/>\nhigh-temperature conditions.<\/p>\n<p>Metal-seated ball valves are commonly used where soft-seated valves cannot meet<br \/>\nthe requirements for temperature, abrasion or media erosion. The QQ41M series<br \/>\ncan be supplied in floating-ball or trunnion-mounted fixed-ball configurations<br \/>\naccording to the pressure, size and operating conditions.<\/p>\n<h3 style=\"color: #123a5a; font-size: 24px; margin: 28px 0 14px;\">\u4e3b\u8981\u7279\u70b9<\/h3>\n<ul style=\"padding-left: 22px;\">\n<li>Designed for high-temperature industrial service.<\/li>\n<li>Metal-to-metal sealing structure for demanding applications.<\/li>\n<li>Optional floating-ball or fixed-ball construction.<\/li>\n<li>Ball surface hardness can reach above 60 HRC after surface treatment.<\/li>\n<li>Optional supersonic tungsten carbide coating.<\/li>\n<li>Optional nickel-based nano-powder thermal spray coating.<\/li>\n<li>Hard material or hard alloy overlay seat construction.<\/li>\n<li>Excellent resistance to wear, erosion and media impact.<\/li>\n<li>Flexible graphite packing for high-temperature stem sealing.<\/li>\n<li>Stainless steel and flexible graphite spiral-wound gasket.<\/li>\n<li>Suitable for abrasive, erosive and high-temperature media.<\/li>\n<\/ul>\n<h3 style=\"color: #123a5a; font-size: 24px; margin: 28px 0 14px;\">\u6280\u672f\u89c4\u683c<\/h3>\n<div style=\"width: 100%; overflow-x: auto; -webkit-overflow-scrolling: touch; margin-bottom: 28px;\">\n<table style=\"width: 100%; min-width: 750px; border: 1px solid #111!important; border-collapse: collapse; background: #fff;\" border=\"1\" rules=\"all\" cellspacing=\"0\" cellpadding=\"0\">\n<thead>\n<tr>\n<th style=\"padding: 12px; border: 1px solid #111!important; background: #eaf3f8; text-align: left;\">\u9879\u76ee<\/th>\n<th style=\"padding: 12px; border: 1px solid #111!important; background: #eaf3f8; text-align: left;\">\u89c4\u683c<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">\u578b\u53f7<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">QQ41M<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">\u4ea7\u54c1\u7c7b\u578b<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">High-temperature metal-seated ball valve<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Ball Construction<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Floating ball or fixed trunnion-mounted ball<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Seat Type<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Metal hard seat with hard material or hard alloy overlay<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Ball Surface Treatment<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Tungsten carbide coating or nickel-based nano-powder thermal spray coating<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Ball Surface Hardness<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Above 60 HRC after surface treatment<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Stem Packing<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">\u67d4\u6027\u77f3\u58a8<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Body Gasket<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Stainless steel and flexible graphite spiral-wound gasket<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">\u9002\u7528\u670d\u52a1<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">High-temperature, abrasive and erosive industrial media<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3 style=\"color: #123a5a; font-size: 24px; margin: 28px 0 14px;\">Floating-Ball and Fixed-Ball Designs<\/h3>\n<div style=\"width: 100%; overflow-x: auto; -webkit-overflow-scrolling: touch; margin-bottom: 28px;\">\n<table style=\"width: 100%; min-width: 750px; border: 1px solid #111!important; border-collapse: collapse; background: #fff;\" border=\"1\" rules=\"all\" cellspacing=\"0\" cellpadding=\"0\">\n<thead>\n<tr>\n<th style=\"padding: 12px; border: 1px solid #111!important; background: #eaf3f8;\">\u8bbe\u8ba1<\/th>\n<th style=\"padding: 12px; border: 1px solid #111!important; background: #eaf3f8;\">Typical Characteristics<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Floating Ball<\/td>\n<td style=\"padding: 12px; border: 1px solid #111!important;\">Suitable for common high-temperature and abrasive applications.
