Principle and diagrams of the stacked pressure relief valve
Thread Content
Recently, I saw a stacked pressure reducing valve on the hydraulic turning device used to rotate steam turbines; it also serves to prevent overflow during startup. I would like to ask: does anyone among you have information or details regarding this topic? Is a stacked pressure reducing valve essentially a two-way overflow valve? !
Reply to 1# ji7058891: It’s a stacked pressure relief valve. I just figured out that it operates in both directions – in one direction it acts as a pressure relief valve, while in the opposite direction it functions as a relief valve
I’m sorry, could you please explain it more clearly? It would be great if there were relevant diagrams to illustrate how it works. Thank you
Do you have any information on stacked pressure relief valves? If so, could you send it to me?
