Scope

This standard specifies the classification and model, materials, structure and connection dimensions, requirements, test methods, inspection rules, marking, packaging, transportation and storage of manual gas valves for construction (hereinafter referred to as valves). This standard applies to non-directly buried gas devices and equipment installed inside and outside buildings with a nominal pressure not greater than 1.6 MPa, a nominal size not greater than 100 mm, an operating temperature not exceeding -20 ℃ ~ 60 ℃, and its lower limit not being lower than the gas dew point temperature. Manual gas ball valves and bottom sealed stopcocks on the facility. The gas referred to in this standard is the gas that complies with the provisions of GB/T 13611.
