Leaking valve pressurized alcohol stove

I have an on off valve on our alcohol stove that appears to be leaking. I think it is from the stem. Is this something that can be repaired or do I need to replace the valve?

If replacing the valve is needed the tubing that connects to it has clamps that look like they are crimped. Is it necessary to use crimp clamps or are hose clamps okay.

A few pics of the valve are below.

Re: Leaking valve pressurized alcohol stove

I separated and pulled the valve out today. There doesn't appear to be a way to tighten the packing. Am I missing something on this or do I need to replace with a new valve?

Looks like the hoses are attached with a tool like this. Of course you can use any other hose clamp.

So just a normal screw type hose clamp should work?
Any idea how to adjust the packing or should I get a new valve? If I get a new valve should the connections for the 1/4 inch Barb's be soldered?
The hose appears to be 1/4 inner diameter.

Re: Leaking valve pressurized alcohol stove

Sorry, I have no experience with alcohol (for heating ).
To be sure I would replace the valve and find an alcohol resistant sealant for the barbs.
For the hose clamps, any good quality SS clamp will do, there is no pressure on that line as far as I understand.
By the look of it it seems that the valve is a three way valve with one exit plugged.

It's a pressurized alcohol stove so the tank gets pumped up to 15 psi Max and is usually around 10psi

I stay by what I posted above, that is low pressure.

Re: Leaking valve pressurized alcohol stove

I suggest trying to disassemble the valve by unscrewing the bonnet where the stem exits. This is the usual construction. It's true, there is no knurling, no flats for a wrench, but if this part cannot be removed, how was the valve assembled? I would clamp the valve in a vise, apply some penetrating oil, tap gently with a light hammer from each side, maybe apply a moderate amount of heat, and try unscrewing the bonnet.

Re: Leaking valve pressurized alcohol stove

I bought a new identical valve to replace this one. Reassembled everything and the new one also leaked at the stem, but this one worse than the original. It will spray alcohol when it is turned. It is okay when it is stationary, but any movement of the stem causes leaks. I tightened it and that didn't help. I'm not sure this valve can deal with pressure and is just to switch unpressurized fuel. I bought a simple ball valve as a replacement and plumbed that in. No leaks now I may need to change my hose routing to mount it, but I zip tied it up for the next day or two until I get a chance to work on it again.

Re: Leaking valve pressurized alcohol stove

I have the new ball valve in temporarily, but I think I'm going to need some more hose to reroute the lines so I can put the valve in a more convenient spot. What type of hose is recommended for an Alcohol stove? I can only find hose that is compliant with E85 gasoline.
