The information about the national standard right-angle carbon steel globe valve is as follows:
1. **National Standard**: According to the GB/T 12235-2019 standard, this standard is applicable to steel globe valves and lifting check valves with nominal pressure PN16-PN420, nominal size DN15~DN400, and operating temperature -29°C-538°C. Steel globe valves for straight-through, angle, and Y-shaped constructions.
2. **Structural features**: The flow channel of the right-angle carbon steel globe valve is a right angle, the valve body and the bonnet are forged throttling type, the sleeve is drilled, and the piston moves up and down in the sleeve to adjust the flow rate.
3. **Technical requirements**: The rated pressure-temperature rating of the valve shall be in accordance with the provisions of GB/T 12224. For some materials with elastomeric sealing pair structure or special treatment of internal parts, the allowable pressure-temperature rating is lower than the pressure-temperature rating of the valve body material, and the lower value shall be taken and shall be indicated on the nameplate.
4. **Material**: The valve body and bonnet are usually made of carbon steel, the valve stem is made of chromium stainless steel, the sealing surface can be surfacing iron-based alloy, and the packing material can be asbestos, graphite, flexible graphite, PTFE, etc.
5. **Performance parameters**: The working pressure of J41H PN160 carbon steel globe valve is 16.0MPa, the applicable temperature is -29°C-425°C, and the applicable medium includes water, steam, oil, etc.
6. **Executive Standard**: Design Code GB/T 12235, Structural Length GB/T 12221, Flange Connection JB/T 79, Test and Inspection JB/T 9002, Product Identification GB/T 12220, Supply Specification JB/T 7928.
