What are the categories and codes for control valves?
Thread Content
May I ask: Valve classification in JB/T 308-2004 does not include control valves. What category do control valves fall under, and what is their code?
Compared to manual valves, control valves consist of various valves to which an actuator has been added; the lower part is the various valves themselves, while the upper part consists of the various control actuators. Examples include control butterfly valves, control ball valves, pneumatic control valves, and electric control valves
I really haven’t seen any symbols on control valves that classify them by valve type.
Control valves are named primarily based on their function; as the name suggests, they are valves that serve a regulating purpose. Adjust quantities such as flow rate, temperature, and pressure difference to meet process requirements. There are many types of valve bodies that can be used as control valves, such as V-ball valves and butterfly valves; the actuators available include pneumatic and electric types.
Control valves fall under the category of automation instrumentation; please refer to the \"Control Valve Manual\".
“GBT 17213-2005 Industrial Process Control Valves” – the poster, take a look at this standard~~
