What are the national standards for cast steel globe valves

Cast steel globe valve is a globe valve made of cast steel. The appearance of globe valve and gate valve looks similar, but they have certain differences. When working, the shut-off valve is of the rising stem type, and the handwheel rotates and rises along with the stem. The gate valve rotates the handwheel and the valve stem moves upwards.



Moreover, gate valves can only be fully opened or fully closed and cannot be used as shut-off valves, while cast steel globe valves can control the flow rate. There are various standards for cast steel globe valves, including international and national standards, and the most common and commonly used ones are some national standards.



The main standards for stainless steel globe valves are:

1. GB/T 12233-2006 "General purpose valves - Iron globe valves and lift check valves"

2. GB/T 12235-2007 "General purpose valves - Steel globe valves with flange connections and lift check valves"

3. JB/T53174-94 "Quality Grading of Globe Valve Products"

4. JB/T53165-92 "High Pressure Balance Stop Valve"

5. GB/T 587-2008 "Marine Blue Bronze Globe Valves"

6. GB/T 590-2008 "Marine flanged cast iron globe valves"

7. GB/T 8464-2008 "Iron and Copper Threaded Valves"

8. GB8465.2-87 "Basic Dimensions of Internal Threaded Gate Valves, Globe Valves, Ball Valves, and Check Valves - Iron Globe Valves"
