    High pressure valve seals

    I have a high pressure fluids application. The valve is a sliding spool type with the pressure acting inside a blind hole in the spool with a side port. When the pressure is reached the spool moves and the port lines up with another in the body and hence flow path is achieved. I'm trying to seal...

    temperature change and pressure rise gradiant for a PRV

    I'm looking for some help. To calculate the temperature change of a fluid (water for example), when its pressurised to 345bar from atmosphere or 3bar maybe, and then what the temperature change would be when brought back to atmosphere again. Pressure rise gradient for a closed valve condition...

    Help with estimating the outlet temp of a fluid through a process

    Firstly, I don't know a lot about heat transfer, that's why I'm here. (and no I'm not a student or studying for any exams etc etc. :) I'm designing a pump system, and the lubrication on the system needs to be cooled using a blast air cooler. The environment is offshore indoors with temps of...

    Help sourcing a PSV for a CRI package (3rd time lucky)

    3rd time lucky (I posted this elsewhere on the forum too) I'm designing a system to pump mud cuttings slurry and am looking for a pressure safety valve to protect the system. The max working pressure is 520 barg and we plan to set the PSV at 572 barg (8294 psig). The pump is a triplex, 8"...

    Post from another section on PSV selection for PD pumps

    I'm designing a system to pump mud cuttings slurry and am looking for a pressure safety valve to protect the system. The max working pressure is 520 barg and we plan to set the PSV at 572 barg (8294 psig). The pump is a triplex, 8" stroke 5.5" plungers, with a damper on suction and discharge to...
