DIY Electric Auto-Sparge

[stamandster]

I was tired of trying to balance two valves during the final sparge/transfer into the boil kettle. So, build a little electric based valve control system. A simple on-off-on switching power to a stainless float valve and motorized ball valve.

Here's an example without water



MATERIALS
- Project Box
- 12v Motorized Ball Valve
- 2 wire cables
- 2 wire connectors
- Power Plug
- Power Switch 115v
- Dual Pole on-off-on toggle switch
- Heat shrink tubing
- 3/8 Silicone tubing
- HDPE Block
- Appropriate tap (m10x1.5) for float switch
- Short Stainless float switch
- Mountable coated magnets
- Various wires, connectors

If anyone wants detailed schematic let me know, I made the box a little large just in case I wanted to add a second one

Woof. I'm impressed, though not enough to ditch my Blichmann auto-sparge valve

Cheers!

@day_trippr Yeah it was a little bit of an endeavor but I mean what isn't with my brewery

Could you describe the functions of the two switches?

 

[stamandster]

The one on the bottom is just for 115v power to the AC/DC power supply, the 3 way toggle is for the valve as on-off-auto (on depending on float switch position)

Could you describe the functions of the two switches?

Have you run a batch through your system with this in place yet?

Cheers!

Nice, did the flat switch provide some histerisys?

No hysteresis, but I use Craftbeerpi for automation, but it's not integrated yet.

Not yet but soon
