T/NXJX 067-2024 Synthetic gas compressor outlet high-pressure cut-off ball valve
Basic Information
Scope
Scope: This document specifies the structural type and basic parameters, requirements, test methods, inspection rules, as well as marking, packaging, protection, and storage and transportation of high-pressure shut-off ball valves for the outlet of synthetic gas compressors. This document applies to high-pressure shut-off ball valves for the outlet of synthetic gas compressors with nominal diameters of DN100 to DN600 or NPS4 to NPS24, and nominal pressures of PN100 to PN400 or Class600 to Class2500, driven by pneumatic, electric, or hydraulic actuators (hereinafter referred to as ball valves). This document applies to mixed gases composed of hydrogen, carbon monoxide, methane, and nitrogen. Other valves for similar applications may also be used as reference.
