Dual-Phase Performance: Manufactured from 2205 Duplex Stainless Steel (S31803/S32205), combining the best properties of austenitic and ferritic steels for high strength and durability.
Superior Corrosion Resistance: Specifically engineered to resist chloride stress corrosion cracking, pitting, and crevice corrosion, making it ideal for marine and oilfield applications.
National Standard Integrity: Designed and tested in full accordance with GB/T specifications, ensuring precise dimensions and flanged connection compatibility.
High Yield Strength: The 2205 material offers nearly double the yield strength of 316L, allowing for a more robust valve capable of handling higher pressure loads.
Full-Port Flow Path: Provides an unobstructed internal diameter to minimize pressure drop and prevent the buildup of solids or slurry.
