    Does anyone have any recommendations on a 2" pressure regulator?

    Ive got some ball fields that are surging and blowing stuff apart. I want to be able to adjust above 75psi, but it looks like the BR-4 above 1-1/4" tops out at 75.

    If your system pressure doesn't exceed 100psi, have you considered using a master valve with a pressure regulator? Maybe a Rain Bird PGA or PEB valve with the PRS-D?

    Just a thought....

    There are also specialty valves that will only open partially, until a set pressure is reached downstream. The idea behind them is to restrict the flow until all the air has rushed out of the sprinkler heads. Big bucks payup

    I agree with Rotor Tool, RB PEB should do the job.

    Sounds like a pressure sustaining valve.

    There might be an additional descriptor, but that's the general category they belong to. I had a client with a golf course that was always having heads blow off their connections, and I suggested he either go to these specialty valves, or parallel the zone valves with much smaller ones and open them first, to let the lines fill.

    Its on a reclaimed water line. Pressure reads 125 but I suspect surges to 150ish. We can't keep the old lines together. Valves keep seeping too. Didn't want master valves because there are multiple field / controllers etc.

    GPM requirement?
    Mainline size?
    Length of mainline?
    If it's a big site then I would probably be looking at some sort of Bermad pressure reducing valve.
