An ISO 15761 gate valve is a high-performance, small-bore linear-motion isolation valve specifically designed and manufactured to meet the rigorous dimensional, material, and testing criteria of the ISO 15761 standard. Governing valves in sizes from DN15 to DN100 (NPS 1/2 to 4) and pressure ratings from Class 150 to Class 2500 LB, this standard dictates a sequential, high-integrity manufacturing chain. The process begins with precision-forged steel bodies (such as carbon steel, low-temperature carbon steel, or stainless steel) to eliminate internal defect risks. Utilizing a wedge or parallel disc configuration moving perpendicular to the flow stream, these valves feature precision-machined, lapped sealing surfaces often hardfaced with Stellite alloys (HRC 35–45) to ensure exceptional erosion and wear resistance. Piping engineers and energy sector procurement networks can guarantee strict small-bore compliance and eliminate fugitive emission risks by importing certified ISO 15761 gate valves directly from leading manufacturers in China via our advanced B2B commercial platform.
