Just thought I would share my experience. I bought an Elk WSV for my office more than a year ago and finally just installed it. Of course it was "defective" and not really new anymore and I just didn't want to deal with warranty. The problem is that it was about 20 degrees off from where it was supposed to be. When "on" it still flowed without any loss of pressure at regular flow rates. However, when off, it still flowed a whole bunch . . .completely defeating the purpose.
So I took it apart. It has 4 cams and 2 limit switches. The cams have set screws with a hex wrench head. There are 2 cams for open spun at 180 degrees to each other and 2 for closed since the vale just keeps spinning in circles making for 2 off positions and 2 on positions. Why they didn't just use 2 cams with "bubbles" on each side 180 degree apart I don't know.
Anyway, First step is to take a sharpie and transfer the "open line" on the "dial" to the top of the stainless post so you know which position it is after you take that off.
To take apart you just pull straight up on the dial on top with the big yellow arrow on it and it pops off. There is one screw that holds the cover on, remove it, and pull of the cover.
Turn power off if you haven't already
Remove the cams by loosening the hex head set screw and sliding them off. You'll need to apply power to spin the valve to various positions that allow access to the set screws.
Spin the valve by applying power to the open wire (or closed, at this point they both do the same thing since there are no cams to hit any switches) until the valve gets to the full open position and then pull the power.
Slide the first cam on and spin the cam counter clockwise on the shaft until the limit switch first "clicks", then tighten the set screw. If you can't get to the set screw, slide the cam off, flip it over and slide it back on.
Apply power to the "closed wire" and the thing will start spinning. Pull the power off when it gets 180 degrees around to the other open position. Slide the second cam on and do the same as you did with the first one.
Now apply power to the "closed wire" and let it spin 90 degrees to the closed position then pull the power. Slide cam number 3 on and do the same as the first two.
Apply power to "open" until it gets to the next open position where it will stop on its own (bottom cam hits its switch). Then apply power to the "closed" wire until it turns 90 degrees to the final closed position then pull power. Add the final cam.
Test it.
Put it back together.
EDIT: I am doing this from memory and there is a small chance the bottom 2 cams are the closed cams, not the open ones. So just make sure that when you apply power to the "open" wire, it stops moving when the bottom cams hit their switch. If I have it backwards, just swap every instance of the word "open" with "closed" and vice-versa.
