How to 'disable' solenoid valve?

[bossteck]

Hi,

Newbie question here.
I am toying with the idea of injecting co2 24/7 but I am currently using solenoid valve.

Is there a way for me to disable the solenoid or do I need to change the valve?

Thanks for any advice.

boss...why don't you change to manual regulator since you intend to have CO2 24/7?

Disassemble the valve. There is a plunger with a rubber seal preloaded with a spring to close the valve. Remove the plunger and the spring and assemble it back.

Hi mok,

This is going to be totally reversible right?

Yes, it's reversible.

Thanks Mok,

I will try to tinkle with the valve... worst case scenario, I will take up aquasynthesis advice and get a manual regulator.

eric,

can't the solenoid valve be detached from the regulator?

[bossteck]

I am not sure, that's why asking here

any photo of your regulator and solenoid?

Hi,
Don't risk the chance of spoilting your solenoid, I am sure you use a timer to control the solenoid, just by-pass your timer to always on, after you had done what you want to achieve and decide to revert back. Just set back your timer.

Turning solenoid to always on would be wast of energy . Ussually, the solenoid should be removable. If I remeber corectly I can removed mine and connect the needle valve directly to the round thing with 2 pressure gauge on top of it.

I'm using the picture that AnA posted at other thread, if it is something like this, you should be able to connect the needle valve (green) to regulator (red). Just need to do un-screwing.

Hi Thomas, mine's a JBL solenoid, think it is quite commonly used by hobbyist. No picture.

Hi Mark,

I am kind of worried powering the solenoid 24/7 would overheat it and actually spoil it in the process.

Hi Shadow,

Thanks for the illustrated explanation, I will go check out my setup and see if I could do what you're proposing.

Will keep everyone posted, but it won't be so soon, probably another 2 weeks or so.

Just adding some more question :

So is the solenoid valve always in closed position due to spring action and is only opened when current pass through a coil above the plunger so that the plunger is being pushed up by the magnetic field?

Is there in market teh valve that works the reverse way? Is this the question?

eric,

you should be able to remove the solenoid. just turn the solenoid valve anti clockwise (regulator pointing away from you; solenoid valve and needle valve pointing towards you)

such valves are available for industrial application. they are called 'normally open' valves where deenergized coil means open valve while energized coil means closed valve.

we use 'normally close' valves where energized coil will open the valve.

OK. That means the the plunger and coil SS NN when energised that repels erach other.

Hello,

During my previous top up, I got the boss at Bioplast to help me remove the solenoid from my co2 set.

After looking at the end results and doing some 'reverse engineering' I figured out how it is done, for those interested.

Apologies for the poorly taken photos, and amaturish editing / labelling. Also, please forgive me if I mis-name any of the parts in the solenoid.

Here goes:
