Low Water Cutoff for thermopile via Ascot valve

HydroNiCK

I want to add a lwc to my thermopile powered 1964 Utica boiler.  Instead of switching to 24v ignition i want to use a 24v solenoid valve before the thermopile valve then hook up a easier to come by lwc to control the solenoid.  Do any of you know the best Ascot or similar valve to use?

Thanks,
Nick

You could just control a relay rated for millivolt switching with the lwco and put it in series with the safety chain on the millivolt valve.

You can just switch the millivolt like the other safety's do. Some low water cutoffs can switch millivolt the M?M #67 can with the right switch or use a relay as @mattmia2 suggested

hot water or steam?

Hot water.  The MM67 is like the only one available.  There may be others but like I said not readily available/ have to search.  That is a good idea.  But id have to find a switch and buy a relay.  I thought the solenoid would be easier and I could get a lwc that looks "cool".  The only prob with the solenoid is id have to relight the pilot after every test unless i put it between the gas valve and pilot?

There are lots of problems with the baso type valve. The relay is dead simple, either control it through 24vac if you have it or add a control transformer or use a relay with a 120v coil and control it with a lwco with 120v contacts.

The relay will be much less expensive than the gas valve as well.
