Hot LPG solenoid

Maybe, maybe not.

Does the owner regularly check the temperature of the solenoid and only recently found it hot?

Most solenoids run hot, some seem almost too hot. It all depends on the power and duty cycle.

If the solenoid was previously running warm rather than hot it could be a problem with the slug or core not moving fully into the coil. When power is first applied there will be a high inrush current that quickly drops off to a low holding current when the slug is in the coil. If the current doesn't drop off it is an indication that the slug is sticking.

Whack the solenoid with the handle of a screwdriver and see if that reduces the current - and heat. Or just replace the valve if it has been around for a long time.

Hi,

Is their no legible wording or numbers on the labels shown on the coil casing?

The solenoid itself is only a tiny component of everything shown in your photo.

Hi,

I am sure you will remember to get all available info should you come across this type of mystery part again.

I am also curious as to why the Regulator and shut off solenoid are remote mounted from the bottle, this means that there is a length of rubber hose in the installation that is under full bottle pressure even when the solenoid is shut off and will remain so till the valve on the bottle is manually shut off.

I just saw the blow up you posted, I see the CE Mark which means the type has been approved for use in Europe - not that it applies to LPG Use. The lower one looks like the Parker Hannifin Logo. Those guys make a lot of fluid control gear, not sure what they do in Gas.

The recall was for leakers.

It would seem to me, that a rubber hose attached with a push barb and a hose clamp on any LPG or LNG system should raise a red flag A reinforced high pressure hose with flared or compression fittings would be a much safer system

Hi,

You should go by your local BBQ retailer and see what connects the regulator outlet to the Grill Valve inlets.

What is down stream of the regulator is a very low pressure and if a proper certified gas hose is used and replaced as recommended by the hose manufacturer there should be no problem IMO.

I believe the top hose in the picture is the high pressure side he commented in post #7 that the stove is on the other side of the bulkhead that would make the low pressure side the bottom hose going thru the bulkhead fitting as seen in his picture in post#3 The hole system looks like an insurance claim to me I wouldn't want it on any vessel I was involved in

Also any regulator that is in a enclosed space should have a diaphragm vent tube from the small hole in the diaphram enclosure to a outside space. This is in case the diaphragm ruptures/fails the gas is vented outside to a safe location. Not all lpg regulators are constructed so that a vent can be plumbed. Regulators intended for outdoor use usually have a screen instead of a threaded vent hole.

Its the HIGH PRESSURE SIDE a swaged on fitting would be infinately stronger

Hi,

I do not know how they do LPG installs where you are from but I have not seen many if any other than the one pictured at the start of this thread where the regulator is remote mounted from the bottle.

This means that the HP side of things is handled by a mechanically threaded connection of the LH Thread type in most cases I have seen except for the odd clip on ones I have seen on a couple of small gas bottles used with cookers in caravans in France.

LPG tanks in US have internal left handed threads, and an external coarse RH thread connection for lift truck fuel ( hi lows) I 'm talking about the connection at the regulator that has a push barb and a hose clamp(per photo) I'm not sure about the inlet side of the regulator threads but a swagged on fitting on the hose, threaded to a fitting on the regulator would be a much better connection

Hi,

I agree with you now you are being specific.

Previously in Post No 10 your statement was a generalisation for ANY system which I was asking what systems you were familiar with if that's how you saw them all connected.

Did you notice that the other hose in the photo seems to have a swaged end to it?

I'm sorry I thought that I was clear that my concern was with the high pressure side of the system. It looks like a normal LPG system to me. Also tirekicker propane is 1&1/2 times heavier than air so the locker vent needs to be at the bottom of the locker
