The AISI 304L Stainless Steel Flanged Globe Valve Type B1 Sealing Surface PN16 is a corrosion-resistant flow control valve designed for moderate-pressure industrial applications. The body is cast from AISI 304L (1.4307), a low-carbon variant of 304 stainless steel that offers enhanced resistance to intergranular corrosion after welding. It features a Type B1 sealing surface, which refers to a metallic seat and disc combination—typically both surfaces hardfaced with stellite or similar wear-resistant alloy—ensuring durable, leak-tight shut-off. The PN16 rating makes it suitable for Application: alcohol, nitrogene, compressed air, condensate,
