I need help with a drink project. I need to improve an item

Projects General Guidance
1

Hello, i'm a beginner in electronics and I have a project i need help with. unfortunately in my country there arent many people with electronics skills and im willing to learn.

The device has 4 gear motors that push a metal bar to shut a water hose, when an RC remote control button is pressed, the gears release the bar and the hose pushes upwards and the liquid is released to a chamber. This is in a very short space. everything works with a 9v battery.

What i want is to change the system to a more reliable way. but i don't know what it could be. i want valves that are specifically designed for liquids to avoid spills.

Forget using a 9 volt battory. I assume it's that kind used in fire alarms. They are voltage sources, not power, current sources.

it's a custom made device for 2oz alcoholic drinks, you press a button and that drink is released into a chamber

Name or picture of the battory, please.

the pictures are already posted above but here they are again

Battory?

Railroader:
Battory?

it's a 9v energizer, it's in the picture. The system works. with the exception of one valve that got broken. i don't want to replace the valve because i would like to have something more reliable instead

Now I see it.
Forget about using that battory! Better things are needed.

What do you suggest? , it cannot be plugged to an outlet

11

Post a drawing, data for the valves, motors, drivers etc.

i dont know how to draw but i will show pictures with details of how it works and details as much as i can

13

Use pen and paper. Take a picture and post it here.

We have 4 2oz containers like this one

Connected to a closed valve like this one

When the valve is open, all of them connect to the same chamber that has a hose that delivers whatever drink i chose

The valves work with this circuit box that is a receiver for Radio Controlled signal, and open when i press the button

Each button opens one of the different valves

15

Post data for the valves, motors, drivers etc. That is needed to figure out what power source You need.
Pictures does not help us.

the valves are these ones

You do the work to dig out data, not me. I use my time for thinking, not digging.
There are more members than You asking for answers to their questions.

sorry for the inconvenience. i lack knowledge on electronics, but i'm willing to learn and to pay for someone to help me improve this thing.

I want to know how much current Your motors, valves etc. will use. That is basic for deciding about the power source.

it's only 4 motors. the motor rotates and physically lowers one metal bar that presses the hose. there are no electronic valves.
