T/NBIPA 003-2025 Technical requirements for solenoid valve thread interface of design and performance
Basic Information
Scope
This document specifies the classification and marking of the threaded interface of solenoid valves used in fluid transmission and control systems with a "threaded base + quick plug" hybrid connection method, as well as the general design requirements, technical requirements, test methods, and inspection rules for such valves. This document applies to the design and manufacture of solenoid valves that use compressed air, inert gases, water, hydraulic oil, and other media, with a nominal pressure not exceeding 4.0 MPa and an operating temperature range of -20°C to +80°C. Other similar application scenarios can be referenced for implementation. This document does not apply to special situations involving the transport of toxic, hazardous, flammable, or explosive dangerous media, unless subject to special assessment and additional protection measures. 1.
