Replacement JVA2440 actuator cable and toggle switch

[zolakk]

I picked up some JVA2440 actuators at a awesome price of $35 each (here if anyone is interested) to work on getting my pool automated but the cables they come with are too short for my needs and they don't have the toggle switch for synchronizing. I already have the replacement plug harness for the controller end, so I just need the actual three conductor wire and I am having a difficult time finding OEM cable anywhere for a reasonable price by the foot anywhere - I actually can't find OEM three conductor cable at all anywhere, just four conductor. I know I can probably just use generic three conductor 22awg cable but i'm a bit overwhelmed at all the options and if there is any special consideration for outdoor use. This is what I currently have in mind but am not sure if it is what I need.

I would also like to add the toggle switch, but I can't seem to find any diagram on how it's actually wired. It looks like a standard DPDT toggle switch from the schematics I can find online and there's no board inside the actuator it's just the wires from the controller wire nutted to the motor wires and capacitor so I think it is just figuring out which wire goes to which tab on the switch. I can post a picture if needed.

Thanks!

The wire you have in the link will work. I extended mine with CAT5 that I had laying around. It might be less expensive to get sprinkler actuator wire from your local big box hardware store than ordering on line. You can add a toggle switch but they are not totally needed they generally provide 2 functions 1.) to define what direction normally closed/open is or put another way the direction the valve swings when energized. This can be as easily accomplished by how you wire the connector reversing red and white. 2.) they give you a manual override/lockout option. Attached is a diagram I found on how to connect one to an external power source and timer it should give you an idea of how to add a toggle if you choose to.

Gotcha, so basically black + white moves in direction 1 and black + red moves in direction 2 while the internal toggle just makes it so B+W = direction 2 and B+R = direction 1 (and middle is nothing connected to bypass control basically) so you don't have to change it on the controller end or rewire the harness. Makes sense now looking at the cam setup so when the cam hits the microswitch it just turns the motor off. For some reason how these work never clicked until just now, makes a lot of sense now.

Thanks for the head's up on looking at sprinkler wire too, i'll give that a look as well.

This is very helpful, thanks.
I'm looking to automate a 3-way valve for some deck jets.
Regarding the switch, I'm thinking about using a wifi relay. If I understand correctly, I would require a self locking one - one that turns On and stays on and then when 'signaled' again will turn Off. Is that correct? [the other option is an inching relay which gives a 0.5sec ON then turns off]. In the later case the circuit wouldn't be closed "long-enough" or permanently to allow the valve to fully move to the stops... if I understand this all correctly... ?

Any comments are appreciated.

thanks.

Correct...set the relay to self-locking mode. Each valve is connected to a single relay. One side of the actuator goes to NC and the other to NO. When off, the NC relay terminal receives power; when on, NO receives power. A limit switch in the actuator cuts power to the motor when the valve reaches it's resting position.
