If I understand your Q correctly, you want to control hot water, right? Not sure about the radiator system or how high pressure or temps get with that, but I was looking for something similar some time ago for hot water (from the water heater). Found a bunch of industrial valve mfgrs that make all types of units for these purposes. Do a web search for "fluid control valves". But then it hit me -- a dishwasher or washing machine does the same thing, so I got one of those units for only ~$25. Application? My home automation has a phone controller interface. Had to do a little bit of plumbing as well, but now, on my way back home from a stressful day or trip, I can dial up to start filling the jacuzzi/whirlpool tub. Nice hot water as soon as I reach home! ----- Original Message ----- From: "BENEDICIC SAMO" To: Sent: Thursday, February 28, 2002 3:25 PM Subject: electromagnetic valve > Hi all! > > Does anybody know where to look for electromagnetically controlled heads for > radiator valves.
