I can’t seem to find much info on solenoids, so I’d thought I would make thread for my own knowledge and to help others.
the hardware on GitHub lists Goyen 3qh/3662. What does the 3662 refer to?
I found the 3qh-sn-v here in the US for a good price($50). But it shows dual inlet versus the sprayer barn part that show single inlet.
then it is already able to accept a teejet nozzle body in 1/2"?
once I have mine setup, I plan to post up close photos to help others.
Thanks for starting this @Titan! I’ve been meaning to compile a list for some time. Solenoids are a real pain and often one of the most expensive parts.
Here I’ve done some work to pull together some suggestions/options to explore. I’ve tried to answer your questions as well.
What does 3662 in “Goyen 3QH/3662” refer to?
Not entirely sure here - these Goyen builds are used extensively in Australia for WeedIT/WeedSeeker custom booms. I haven’t seen them advertised online. The only place I ever saw them for purchase was in SprayerBarn in Moree/Narrabri. The 3662 likely refers to that custom arrangement where the Teejet nozzle body is directly integrated into the solenoid.
I found the 3qh-sn-v here in the US for a good price($50). But it shows dual inlet versus the sprayer barn part that show single inlet.
I couldn’t seem to find any photos/specs of that part number online - do you have any links/photos of it? Goyen was originally an Australian company so I wonder if there is a much greater range there. They are fantastic value and perform well too - so if you can find a supplier that works, it’s worth going that direction. These are how we’ve used them in some of the first builds. Dual inlet was fine - we just used single inlet on the ends with a tap to purge the line.
Besides Goyen there are other options I’ve tried to list below. I haven’t tried them all, only a handful - but would be good to eventually build up some community experience on these.
The OWL driver board has 4x 2A outputs at 7 to 26V, though each output supplies the input voltage to the load when active. It means that you effectively need 12V valves to make this work. ISOBUS or CAN type valves need more complex controllers.
Distance column = response time x 2.78 m/s (10 km/h). It is the ground covered before the valve has actually opened. If you combine this with the frame processing speed (frames per second) and MOSFET switching speeds you end up with an estimate of how fast you can travel for a given field of view.
| Image | Option | Fits | Response time | Distance @ 10 kmh | Flow, pressure, draw | 12V switch | Price | Experience |
|---|---|---|---|---|---|---|---|---|
| TeeJet 191500 DynaJet | TeeJet bodies with diaphragm check valve: -1 for QJ200/300/8360/17560A, -2 for QJ360C/370, -4 for QJS, -6 for Wilger | 6 to 12 ms, PWM approved | 2 to 3 cm | 0.6 GPM at 5 psi drop, 0.8 GPM at 10 psi; 100 psi max; 0.9 A (10 W) | Yes, 2-wire coil | Barndoor Ag USD 125, Dultmeier USD 139, EU EUR 253, AU AUD 478 | Expensive options, but drop in and fairly good quality on TeeJet diaphragm check valve nozzle bodies | |
| TeeJet 116280 DynaJet High Flow | All TeeJet bodies | 6 to 12 ms, PWM approved at 20 Hz | 2 to 3 cm | 1.0 GPM at 5 psi drop, 1.4 GPM at 10 psi; 100 psi max | Yes, 2-wire coil | TeeJet spec page | Same speed as 191500 with 1.7x the flow. | |
| TeeJet 116950 e-ChemSaver ES | All TeeJet bodies | 12 to 20 ms, not PWM rated | 3 to 6 cm | 0.7 GPM at 5 psi drop, 1.1 GPM at 10 psi; 100 psi max | Yes, 2-wire coil | TeeJet spec page | On/off only, slightly slower. OWL does not need PWM, so this works if it is cheaper locally. This is what we have on our current 12m sprayer | |
| Capstan Spitfire / PinPoint assembly | TeeJet 15-series (116500-255), Arag/Hypro (116500-256), Wilger (116500-257) bodies | Not published but runs PWM at up to 30 Hz | approx. under 5 cm | 7W coil, (approx. 0.55 A) also 12 W option | Yes, 2-wire coil | SpraySmarter USD 237, Arag version on special USD 146, Canada CAD 300 to 323 | Untested on the OWL and hard to find info on. The PinPoint II manual has most details on install and differences between models | |

The ones we got from SprayerBarn Narrabri had direct integration with the Teejet Nozzle body. They | |
| Goyen 3QH/3662 (SprayerBarn, AU) | Base modified with TeeJet nozzle body attachment | Not published | Not published | 12V DC Coil | Yes, 2-wire coil | SprayerBarn, price not online, parts list on GitHub Issue #2 | The original ute boom part. 3662 is a Goyen build number, not a spec. | |
| TIR NB.2602A.WP (Texas Industrial Remcor) | Standalone; 1/4" NPT inlet, 1/4" NPT nozzle body outlet | Not published | Not published | 1 GPM, 80 psi max, 0.85 A, Viton. Also NB.2601A (125 psi, 1.1 A) and NB.2603A (0.5 GPM, 175 psi); 24V versions exist | Yes, 2-wire Weather-Pack (12V versions) | TIR USD 98, Spray Parts Warehouse USD 74 | Closest US analogue to the Goyen, used on Flux Robotics platform | |
| Hypro ProStop-E | Is the nozzle body (5-way turret, 3/4" or 1" pipe); valve-only version fits Hypro ProFlo bodies | 180 ms close to open (Hypro) or 250 ms quoted by retailers | 50 to 70 cm | Electric ball valve; 2.0 GPM at 5 psi drop; 150 psi max; 250 mA actuating, 30 mA holding, 9 to 16 VDC | Is designed for ISOBUS control, but can be operated in analog mode by switching the ‘analog pin’ - which is not specified | Mid-South Ag USD 104, Hypro page and manuals | Untested on the OWL, but seems slow and you need to workaround the M12 connectors | |
| Hypro ProStop (pneumatic) | Any body with 3/4" BSP check valve thread | Fast, air actuated | Small | Needs compressed air | Indirectly: OWL switches an air solenoid | Pump Works GBP 13 | Only makes sense with a pneumatic manifold design. | |
| Goyen ST2 series (AU) | Inline 1/2" or 3/4" BSP x 1/2" barb | Not published | Not published | 65 L/min, 150 psi, Viton | Yes, 2-wire coil | Spraymart AUD 125 to 139, Sprayer Warehouse AUD 120, Farmco AUD 157 | These are likely quite slow - untested on the OWL. Not entirely sure how well they will work and may be more suited to section control. | |
| Bürkert Type 6013 | G1/8 or G1/4 threaded, brass or stainless, FKM seals; own mount needed | 20 to 30 ms | 5.5 to 8.3cm | 2 to 6 mm orifice; 12V DC coils available | Yes, 2-wire coil | Bürkert UK GBP 73 to 166, Bürkert US USD 110 to 240 | Industrial option, not necessarily ag-relevant. Untested on the OWL. | |
| Arag Seletron | Arag nozzle holders | 400 ms | >1m | Motor-driven diaphragm valve; 8 bar (115 psi) max; 0.32 A at 12V; Viton diaphragm; 175 g; 0 to 60 C | CAN-bus but you could hijack the 12V pins | Arag | Not recommended for a relay output | |
| Generic 12V brass/aluminium/nylon solenoids | Threaded; own mount needed | Not published, often pilot operated and slow | Unknown | Small orifice | Yes, 2-wire coil | eBay or Amazon USD 10 to 40 | I’ve used these for demos - they are cheap, but very limited and unreliable | |
| Fuel injectors | Full custom plumbing | About 1 to 2 ms | Under 1 cm | High-impedance (12 to 16 ohm) types draw about 1 A; low-impedance and common-rail diesel types need peak-and-hold drivers | High-impedance yes; low-impedance no | AliExpress/eBay | Used on VegOWL with mixed success - the concept works but we switched to non-brandname solenoids from China that work great. The injectors were not drilled straight, so aligning with the weed was very difficult |

Would love to keep building this table out with examples/better info. If one is missing or has incorrect data please comment below and we can start to assemble solenoid info into one spot.
Great Information!!
The source for the Goyen solenoids called me and said they no longer carry them here in the US.
The problem here is you are just about locked out of accessing items like this directly. You almost always have to go through a dealer and they tend to be not only pricey, but extremely hard to work with. There is no problem solving, just replacing parts for a specific sprayer they sell.
Ag sprayer solenoids seem to run $250+ each. Looks like most are copies of the Texas Ind Remcor.
I am going to try 2 solenoids that are not on your list yet:
Norgren 12v solenoid - no real data here. $90 each
US Solids 12v Solenoid - Looks like a 300ms response time. $32 each. Stainless Steel with 1/4" up to 1/2" size. I’ve used their 24v ball valves with good success.
