I bought this zone valve to fix a faulty Dole HM-4 on a Weil-McLain P-FG to replace boilers of the 2 series. The valve he replaced gave me problems for a long time and finally got stuck in the open position. Since they no longer make Dole valves I had to replace them with another brand. The Honeywell V8043E1012 best matched the specifications of my broken valve. It was easy to install and the wiring was fairly simple. I've had it installed for a week now and it works like a champ. The temperature in this zone is now stable, it used to fluctuate quite a lot before the old valve completely stopped working. It remains to be seen if this valve will last as long as the 35 year old valve it replaced, but so far I'm happy with it.
