Problems with flow control valves
Thread Content
I previously posted a question: “Why are the control valves for the circulating water in heat exchangers usually located on the return water side, while the control valves for steam are generally located on the steam supply pipe? I think it’s not just a matter of convention.” One user replied that the control valves for the circulating water in heat exchangers are typically pressure control valves. And the steam supply control valve is generally a flow control valve. I’m not sure if it makes sense, so I’m coming here to ask for advice. I was wondering if you could provide a detailed explanation (information about these two types of control valves and the differences between them). Thank you!
For heat exchangers, the control valve for the circulating water is usually installed on the return side; installing it at the inlet can affect the cooling efficiency. As for steam valves, they are generally placed in the steam supply pipe – installing them at the inlet improves response speed, while installing them at the outlet results in a slower adjustment speed
