Hi I am new to this group and only looking into this OWL system i did look into somthing like ths before but it was way out of my price range.
I am just wondering what people used to control the sprayer nozzle valves. i am wanting something that i can remove the anti drip valve and install a PWM valve in its place. have any one done this before and what would the cost be.
Welcome! Thanks for posting here.
Which nozzle body are you using? The most plug and play I’ve used for that are the TeeJet e-ChemSavers. They can mount onto teejet or arag nozzle bodies in place of the anti drip valve. But they cost about 200 to 300 eur each…
Capstan solenoids are probably the best alternative/standalone option - I haven’t tried these myself, but they have been recommended a few times. They seem to run about USD150 from one store.
There are likely to be cheaper, mass produced alternatives to these - it is a surprisingly expensive part of the system though.
I am using the Teejet body. The cost is what i was worried about and you have now confirmed my fear.
I will get a look at the capstan solenoids. My sprayer is a 24m but to start with i want to make up a OWL system for spot spraying using a UTV along with my Agopengps autosteer before i go bigger.
The cheapest no-name versions I have seen around about $50 to $100 USD, but it seems most get them custom made in China. Could be worth exploring.
Consider contacting SprayLogics - they mentioned they might be selling some. Not entirely sure though.
For the VegOWL system we used diesel injectors that were ok, but would require a complete redesign of your system. I have tried the cheap 12V solenoids before but they are quite rubbish.
Good luck with the build! Keep us updated here with how it goes and if you run into any issues.
