Y Strainers

in THE MAIN WALL
that you mean wye strainers in a PRV steam application such as one might find using utility steam. Anyway, I do something a little different. I drop the blowdown outlet piping as a dirt leg and trap it to keep it free of condensate. Eliminates the issue. (The trap, usually a 1/2" or 3/4") has it's own Wye Strainer of course for it is in harm's way). The blowdown leg terminates in a full-port ball valve for flushing the main strainer.

Otherwise, I agree, basket to the side to keep a water pocket from collecting.

    Y Strainers

    First let me say that I have gazed this site for a few years now and know that there are many talented proffesionals here. I am hoping to hear opinions from some of them on piping methodology for PRV stations I have seen some manufacturers recently that are calling for y strainers on PRV stations to be installed on their side. After having it explained to me it does make sense. The theory is that the strainer should be installed on its side, rather than in the conventionial way with the screen hanging below the pipe. This is to avoid the screen space acting as a collection pocket for condensate. Water that collects in the strainer when the control valve is closed will be carried into the valve when it begins to open. This water when forced between the valve disc and seat of the just opening valve can lead rapidly to what the manufacturer refers to as "wire drawing" ultimately damaging the disc and causing failure.
    Would like to hear your opinions.

    Correction.. I said install PRV stations on their side but just meant to say Y strainers.

    Yes, the strainer in reference would be spelled as wye. A ball valve on the blow-down is great if the facility maintenance personnel will actually use it. Thank you for the response

    Oh, I did not mean to correct your spelling

    of Wye- that is just how I spell it myself! Rather, I was just outlining the application.

    People who deliberately correct the spelling of others -and make a point of it- give certain terminal bodily orifices a bad name.

    No problem. No offense was taken. It's one of those old habits that I can't shake.
