These are acceptable in most industrial processes. The benefit of metal seats is that they do not age, swell, or harden as polymers do. This makes them reliable for long-term sealing stability.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Temperature_Range\"><\/span>2. S\u0131cakl\u0131k Aral\u0131\u011f\u0131<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Soft seat valves fail when they go beyond their material limits. EPDM degrades when subjected to temperatures above 120\u00b0C. PTFE is limited to 200\u00b0C. Beyond those temperatures, metal seated valves are required.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Metal seated valves are temperature resistant from -196\u00b0C to 600\u00b0C. Alloy seats can withstand high temperatures, which makes them suitable for power plant steam lines and refinery distillation units.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Austenitic stainless steel can withstand very low temperatures, which makes it suitable for a <strong>cryogenic butterfly valve <\/strong>in LNG terminals and liquefied gas service. PTFE and rubber can freeze and shatter in very low temperatures.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Pressure_Rating\"><\/span>3. Bas\u0131n\u00e7 De\u011feri<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Soft seated valves can operate within PN10 to PN16 pressure classes. This makes them suitable for water supply and light industrial lines.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Metal seated designs can withstand PN25, PN40, and higher pressures. They are suitable for high-pressure steam, gas transmission, and hydraulic systems.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Abrasion_and_Corrosion_Resistance\"><\/span>4. A\u015f\u0131nma ve Korozyon Direnci<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Soft seat valves are prone to erosion and abrasion. Particles such as fine sand or catalyst fines scratch the soft seats and cause premature leakage in rubber or PTFE-seated valves.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Metal seats coated with Stellite (cobalt-chromium alloy) are resistant to particle erosion. The coatings protect against chemical attack in acid, alkali, and oxidizing environments.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Service_Life_and_Maintenance\"><\/span>5. Hizmet \u00d6mr\u00fc ve Bak\u0131m<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Normally, a soft-seated valve lasts three to five years before the seat needs replacement. The soft seat is easier to replace than a machined metal seat. However, soft seats degrade faster in harsh conditions and require more frequent maintenance.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Metal seats last more than ten years in demanding service due to their protective coatings. Repairs are more expensive, but maintenance intervals are longer.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_Cost\"><\/span>6. Maliyet<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Soft seated valves are 30% to 50% cheaper because their material and machining requirements are simpler. Metal seated designs are more expensive. They require precision machining of offset geometries and application of wear-resistant coatings.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your project has high-temperature or abrasive service, it is more cost-effective to invest in a metal valve seat. This results in reduced downtime and fewer replacements.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7_Structural_Differences\"><\/span>7. Yap\u0131sal Farkl\u0131l\u0131klar<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Soft seated valves typically utilize a concentric (centerline) design where the disc and stem share the same axis. On the other hand, metal seated models use double or triple eccentric geometries. This helps minimize seat contact during the stroke, which is vital for maintaining a durable metal-to-metal seal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because the disc wedges firmly into the metal seat, these designs require higher operating torque.
