Here&#8217;s what to check before placing an order.<\/span><\/p>\n<h2><b>Ball Valve Design Types<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Floating ball valve<\/b><span style=\"font-weight: 400;\"> \u2014 the ball moves slightly under pressure to seal against the downstream seat; common in smaller sizes and lower-pressure applications<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Trunnion-mounted ball valve<\/b><span style=\"font-weight: 400;\"> \u2014 the ball is fixed in place by a trunnion, with the seats providing the seal; used in larger sizes and higher-pressure applications where floating-ball designs aren&#8217;t practical<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Full bore vs. reduced bore<\/b><span style=\"font-weight: 400;\"> \u2014 full bore matches the pipe&#8217;s internal diameter (lower pressure drop, allows pigging); reduced bore is more compact and economical where flow restriction is acceptable<\/span><\/li>\n<\/ul>\n<h2><b>Materials and Pressure Classes<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Common body materials include carbon steel, stainless steel (304\/316), and alloy steel for higher-temperature or corrosive-service applications. Pressure class (e.g., Class 150, 300, 600 per ASME B16.34) must match your piping system&#8217;s design conditions \u2014 confirm the manufacturer&#8217;s stated pressure class aligns with actual third-party test data, not just a catalog number.<\/span><\/p>\n<h2><b>What to Verify Before Ordering<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Seat material<\/b><span style=\"font-weight: 400;\"> \u2014 PTFE, RPTFE, or metal-seated depending on temperature and service;
