How long can the solenoid valve typically be kept open for before it gets too hot and how much time should be allotted for cooldown between uses?

I haven't found the limit of the solenoid, but after about 15 minutes I realized I had melted my circuit board a little. It only took about a minute to get hot enough to start melting the plastic on the circuit board.

I have used them as safety valve and had them wired to normally closed e-stops and left them on for 6+ hours at a time. But the true duty cycle I don't know

if wired RIGHT,, proper sized transformer or circuit board relay.. the solenoid should be able to be always on,, example a nat gas solenoid valve stays always on, the fire system would then shut off gas when emergency,, always try to find info/data sheet

I didn't like the heat so I cheated.I used a 10,000uF capacitor in parallel with ~10 ohms in series with the 12V and valve.This allows the full 12V available to pull in the valve, but then drops the current by around half, reducing the power to ~1/2 of normal.I was afraid to let the valve operate for more the about ~15 minutes with 12V.Do a net search for fast relay operation or reducing relay power consumption for some examples.Good luckTerry

Long time so far. I am sure it depends on how often you open and close the valve. Standby mine have lasted 6 mo. so far.

If it can't be plugged in overnight how long would I have to leave this plugged in for so that the engine is warm enough to start easily and not cause premature wear on the engine?

Hold the red button down until the thermocouple has heated up, probably 10 seconds, that allows the gas valve to remain open

We have left this in the truck in mod hot temps (80s) for several weeks w/o a problem, but when it started getting into the 90s, we brought it inside. I don't trust it for a long period of time in extended heat.

I wish I knew, because this is a common problem. But I have a suggestion. When you are done using it, donot turn it off! Turn it on the coolest setting, zero I think, and let it cool down with air blowing through it. About 45 minutes. Otherwise you will burn up the heating element!

I don't think it's normal. That is why I returned mine. Would not run for more than a few minuets before overheating and the safety would shut it off. I know of people who have had success with it but not me and looks like not you either. I'd return it because overheating that quickly could lead to blown fuses or fire.

Start by pressure testing your radiator and cap. If the cap is bad, stop leak won't help. If there is leakage in the head gasket, the stop leak might help. Start off with 1/4 to 1/3 of the bottle and make sure that you run your heater for the first 100 to 150 miles so that the sealant circulates through the whole system. This will reduce the possibility of clogging the tubes of the heater core and seal external heater core leaks too. After a week or two, you may need to add more coolant. Add 1/4 bottle of the stop leak if you add more than a pint of coolant. Follow a week or two later the same way. If after 3 months you are still loosing more than a pint a month, you need to look deeper into that cooling system.

I was able to do it on mine and use it to fill a hillbilly hot tub at my cabin where it needs to run for a couple hours, which it does with no problem. It is possible to rewire the solenoid but I would be very careful if you attempt this and verify that the other safety features still work.

Other thing is that the solenoid must be completly tight to be used with the computer. You only turn this maybe 180deg maxs to manually open the valve. If you turn more water start leaking. This is normal.

The one I have can be set on high, low or keep warm for 2 or 4 or 6 or 8 or 10 hours.At the end of the set time it automatically switches to keep warm.It's the 4 1/2 quart oval with the sensor probe. So far it works just fine.

i have no problem. A little bit make a noisy. YES, about 20 minutes overheats, i do like this. main switch turns off and then onand use.

Ive used the unit several times, and for a good/long amount of time each use. So far I have not had any overheating issues.

The solenoid work best if you connect it to a timer. When the timer is ON, the solenoid will open as well - letting the Co2 pass through. When the timer is OFF, he solenoid will close stopping the flow. In my case I have it connected to the same timer that is running the lights, so when lights are on the bubbles start flowing, and they stop as soon as lights go off. It is not configurable, the power will make it open, lack of power will make it close. What you can configure or change is the flow rate.

I don't know, I have not test but is a small solenoid on function only on one side; ex.: for the main tank always on with no current and on ( 12V) when is for the auxilliary side. So if you run on the main you don't use current.Regards

I'm not sure of the exact amount of time, but I'd estimate several hours with constant use. I've had no issues with it becoming too hot...something I noticed frequently when I had an hp.

Can be stored indefinitely as long as they are not punctured and use depends on a lot of things...elevation valve setting (wide open or throttled) but frugal use I have got around 7 hours of cool time
