low relay resistance coil

Hi to all. I replace a AC compressor using a magnetic valve the resistance was 11 ohms now i need to use a relay to replace the valve I tried a bosh relay with 85 ohms but it will not activate the relay coil do you know of a relay with a resistance close to the magnetic valve or some thing I can used ??

What voltage & current rating for the contacts? What coil voltage rating?

Thank for the quick reply.I Did not check voltage nor current but I believe it's 12 volts it's operating the compressor coil witch is 12 volt 4 ohms but is burning the compressor coil because current is to low.Do you know of any relay operating on 11 ohms??

Is the coil in series with something? I don't understand the situation.... If the relay's coil load has to be something specific (but why?), then just add a parallel resistor (eg, say a 12 Ohm 20 W resistor for 12V). And you can't use a relay to replace a magnetic valve. Do you mean replace a relay that controls the valve, and the valve has 11 Ohm resistance? (That's ~1A @ 12V (hence 12W) but most relays will handle that - eg, automotive Bosch-type 15A or 30A relays that have a typical coil resistance of 60 Ohms or more....     But be sure of the voltage... if it's a 120V or 220V AC compressor/system/relay then using 12V stuff is DANGEROUS!

OK since you from Australia You know the 2005 Toyota hiace Lwb it has an electronic AC compressor with a magnetic valve now I have change it to an electrical compressor but relay will not work.

Nah - sorry, I only know of mechanical aircons with electric clutches driven off Vee or serpentine belts etc (and Peltier devices, but hopefully not for aircon!), and the various interlocks like idle cut-off (of the clutch) or fast-idle etc. I'm not aware of valves per se - except for bypass (maybe during idle) or pressure relief etc. Again, sorry. I'll leave it to someone that understands....

Thank for the help maybe a Transistor will do the job. Do you know about transistors??

Yep. Not that I see how it helps..... If you want switching - use a MOSFET. If you want resistance, use a resistor.

wth is a magnetic valve? I've never seen one in an automobile AC. You won't find ANY automotive relay under 85 ohms coil resistance, the first poster is looking at another problem. Florida? Every gas station has an AC expert, go to one.

Problem solve a resister across the relay coil was it
