I'm going to revive this thread since I was just looking at using a Griswold DWS valve for use as a master. It is a bit cheaper than the 8200CR and has no screens to clog. Anyone have any experience with these valves?

I was not aware Griswold was still around..they were a player years ago &
I believe they had a pretty advanced (for its time) controller. Got a link?
The 8200 valve is sweetness..goes with the Calsense.

Ewing carries all their valves. The DWS and DW-PRV are all brass construction.

Thanks Kiril, I'd forgotten about them. Notice they make a normally open
valve, I thought Superior was the only one. We use them on the Rain Master
sites w/ flow sensing.

Curious if you run two masters in the above senario?

The MC+ is right up there with those brain-strainers.
That Johns Manville was the because P.I.T.A. of all to program.

Not a bad idea, because you could program for it, but no, a normally open
MV when quick couple or faucet lines are spec'd.

I didn't read all of the posts but I'd say the hardest "clocks" to work with was the old hydraulic manifold Toro's like the VT-1 thru 4 series.
I used to service these old controllers on a golf course near me and they were always clogging at the junction inside of the cabinet. To clear them you had to have REAL quick fingers as the moment the line was separated the damn head popped up.
The cams always stuck and until one became proficient in knowing how much pressure to apply the risk of striping the teeth was a constant concern.
Not to mention every station in every satellite had to be timed perfect to avoid overlapping the run times and screwing up the coverage from too many heads running at the same time.
I still cringe when I hear that ratcheting noise.
