    Choosing the right valve for the pressure

    Thank you very much. I figured that this would be the best place to post the question but I could try to post on the hydraulic valve section. Thank you all again.

    Choosing the right valve for the pressure

    Tim, I see. I would say that the system that this valve is on, will only be used when the airplane is on the ground and for no longer than 3 minutes at a time. I work on conversion airplanes here in Tampa FL. I figured that valves get tested for a higher rating PSI but i wanted to get some idea...

    Choosing the right valve for the pressure

    Thank you guys for your response. The Aircraft does run on 3000 PSI but it will never exceed it by more than a couple 100 PSI. I have valves that are rated at 3000 PSI but i was unsure if the was the minimum that i should use. Tim had mention safety factor may be greater than industry standard...

    Choosing the right valve for the pressure

    Hello all, I am wondering if there is a standard multiple # that people use to determine the right valve max operating pressure for a system delivery a specific pressure (3000 PSI as an example). For example a 737-300 runs hydraulic pressure at 3000 PSI. I am wondering if a valve rated at a...

    2024-O vs 2024-T3

    Ok. So depending on the type of forming that i want to do. Will (more or less) reflect the choice between T3 or T42. Like for a sharp bend I should use O then HT42 but, if what i am looking for is almost (degree < 30 degrees) or a very small angle of degree then T3 is recommend. Moreover, its...

    Commercial jet Tire expansion

    Hello, I am inquiring about the use of a proper formula to use to find out the expansion in a commercial jet as they take off during flight. Like, a standard expansion or a range. What comes to mind is some form of a normal/tangential formula to find the change in displacement and this way i...

    2024-O vs 2024-T3

    Hello all, again, for information because it can be confusing. I can see the confusion in the question. What i would really like to know is the reasoning behind why you can substitute 2024-T0 HT42 with 2024-T3. I have talked to some of the machinist at my job and they have said that they are...

    2024-O vs 2024-T3

    Hello, I like to know if 2024-T3 requires heat treat to T42. I have decided to use 2024-T3 instead of 2024-O which required the heat treat to T42 but i am not sure if the 2024-T3 requires it?
