Casting gate valves are produced by pouring molten metal into molds, making them more cost-effective for larger sizes (2\" and above) and standard-pressure service.<\/div><\/div>\n            <\/div>\n            <div class=\"faq-item\">\n                <button class=\"faq-q\" onclick=\"toggleFaq(this)\">What is a bellow seal gate valve?<span>+<\/span><\/button>\n                <div class=\"faq-a\"><div class=\"faq-a-inner\">A bellow seal gate valve uses a metal bellows welded to the stem and bonnet to create a hermetic seal, completely preventing fugitive emissions through the packing area. It is widely used in toxic, flammable, radioactive, or environmentally sensitive applications where zero leakage to atmosphere is required.<\/div><\/div>\n            <\/div>\n            <div class=\"faq-item\">\n                <button class=\"faq-q\" onclick=\"toggleFaq(this)\">Can XINTAI provide custom gate valve solutions?<span>+<\/span><\/button>\n                <div class=\"faq-a\"><div class=\"faq-a-inner\">Yes.
