Engineered in accordance with API 600<\/strong>, ASME B16.34<\/strong>, ASME B16.5<\/strong>, and API 598<\/strong>, this valve is widely used in LNG terminals, industrial gas plants, petrochemical facilities, offshore platforms, and cryogenic storage systems. The full-port wedge gate design ensures minimal pressure loss and dependable bidirectional shutoff.<\/p>\n F316L is a low-carbon austenitic stainless steel known for its excellent low-temperature toughness and corrosion resistance.<\/p>\n Low-temperature valves typically utilize an extended bonnet to:<\/p>\n This design is especially important for LNG and liquid gas applications.<\/p>\n The flexible wedge provides:<\/p>\n Raised Face (RF) flanges offer:<\/p>\n The gate valve uses a linear motion mechanism to control flow.<\/p>\n Because the gate moves completely out of the flow path when fully open, pressure loss is extremely low.<\/p>\n Widely used in:<\/p>\n Suitable for:<\/p>\n Applied in:<\/p>\n Used in:<\/p>\n F316L is preferred for corrosive and cryogenic applications where long-term reliability is critical.<\/p>\n Each valve undergoes strict quality assurance procedures:<\/p>\n Ensures body integrity and pressure resistance.<\/p>\n Verifies shutoff performance.<\/p>\n Performed according to BS 6364 upon request.<\/p>\n Confirms F316L chemical composition.<\/p>\n Yes. F316L stainless steel retains excellent toughness and ductility at temperatures as low as -196\u00b0C.<\/p>\n The extended bonnet isolates the stem packing from extremely low temperatures and prevents icing.<\/p>\n API 600, BS 6364, ASME B16.34, API 598, and ASME B16.5 are commonly used.<\/p>\n Yes. F316L low-temperature gate valves are widely used in LNG storage, transportation, and processing facilities.<\/p>\n LNG, industrial gases, petrochemical plants, offshore platforms, and marine fuel systems.<\/p>\n We provide:<\/p>\n \u2705 API 600 & BS 6364 Compliant Manufacturing Please provide:<\/p>\n
