in THE MAIN WALL
I am trying to find a 4" prv 8 bolt flange. Watts doesnt make any that big. I was wondering if anyone could help me find a manufacturer that makes one of this size. There is an existing one in place but theres no tags to identify the one thats in there now. Any help would be greatly appriciated. Thank you

    Pressure Reducing Valves

    I think that you'd use a large diaphragm valve, with a small pressure reducing valve acting as a pilot valve. This is a PRV set manufactured by RWC (http://www.rwc.co.uk), but I don't know if their products are marketed in the US.
    I've used Aquatrol/Osmonics diaphragm valves, they probably make one in the size you need.

    There's some useful technical 'training guides' about PRVs that can be downloaded from the RWC site. Sorry this is so late, my memory can take a while to retrieve information.
