Hunter 458200 Battery Operated DC Latching Solenoid
The Hunter 458200 is the DC Latching Solenoid for Hunter valves. These solenoids are only used on valves with the SVC or WVS battery operated systems. The Battery operated SVC and WVS systems use DC instead of AC electrical supply. These DC solenoids replace the AC solenoids that come standard on a Hunter valve. Designed to fit all Hunter Plastic Valves.
A battery-operated controller sends a quick DC pulse to operate the solenoid, therefore the battery-operated controller requires a DC latching solenoid to operate correctly. Also, the DC latching solenoid will have one black wire for the common wire and one red wire for the station wire. It is important that the wires are connected correctly for proper operation. Black connected to the C or COM (common) terminal inside the controller, and the red wire connected to the appropriate station terminal.

9v alkaline battery.
There does not appear to be a technical manual nor any electrical specifications available online. In one of the online papers on irrigation
(F.R. Miranda, R.E. Yoder, J.B. Wilkerson, L.O. Odhiambo) they reference the Rain Bird solenoid as requiring pulses of 100msec at 12v and Hunter claims that the SVC controller is capable of using the Rain Bird solenoid. In summary what I have seen on the web suggests that 50 to 100 msec pulses at 9v with the correct polarity should be sufficient for proper operation.
The preceeding information has yet to be field tested and should be taken as only slightly better than gossip.
You need to have a battery operated controller which is separate from the valve. The battery operated dc latching solenoid is inserted (or screwed into) the valve. The wires of the solenoid are connected to the wires of the battery operated controller with waterproof wire nut connectors.
My own experience will probably not help you much. I run the controller on batteries. The farthest valve is only about four feet from the controller, which is in the ground next to a couple of other valves.
I hope this info helps you.
Battery operated DC LATCHING SOLENOIDS are special case solenoids that operate on low current (< 100mA) DC voltages. Since the solenoid is a "latching" type, you would provide a DC "Pulse" to open the valve, and another DC "pulse" to close the valve. I believe the pulse width is <= 2ms. So if you were to provide a 12VDC @100mA signal for 2ms the valve will open, one more 12VDC @100mA signal for 2ms and the valve will close. If you connect a DC latching solenoid on an AC source, I imagine the valve might try to open and close at the rate of 60 times per second for as long as that AC controlled station says the water is supose to be on. I doubt you would ever want to do this and I doubt the solenoid would survive very long if it works at all. In addition, 24 volts would drive the solenoid too hard and ruin the valve. Again, if this would even work at all.
You want to replace your original 24Vac solenoid with a 24Vac solenoid. You NEVER want to try to replace an AC solenoid with a DC type solenoid and you would NEVER want to try to replace a DC type solenoid with an AC type solenoid..
I'm surprised you even have a DC Latching solenoid since these are usually considered special order items for DC watering systems which I think might be commercial systems.
In Arizona, we have such hard water, that we usually have to replace the entire VALVE every year because the valve eventually will not close all the way because of all the calcium build up. All my valves use couplers so that changing a valve is as painless as possible.
SVC-100 manual: Baccara G75-0-1002
Rain Bird TBOSPSOL
Specs I found for the Rain Bird: 150 psi maximum operating pressure
• Solenoid Dimensions:
o Width: 1 3/8" (4,0 cm)
o Height: 2 3/8" (6,0 cm)
o Depth: 1 1/2" (4,2 cm)
For use only with valve controllers designed for latching solenoids such as Hunter NODE-100 single station controller
The product "Hunter 458200 Battery Operated DC Latching Solenoid" is just the solenoid and not a valve. This part just allows a battery operated (dc) controller or timer to communicate electronically with the valve, opening and closing it as programmed. Usually, hardwired controllers use ac, or alternating, currents while battery powered controllers use dc, or direct, currents.
For assistance on internal parts and quality of valves I would suggest researching the website of the manufacturer you are interested in. Search for parts breakdowns, parts lists, etc. Toro, Hunter, and Rainbird all provide detailed scaled drawings and parts break downs for all of their current valves and other irrigation products. These can be found in .pdf form on their respective websites. They will help in showing you how the valves can be taken apart and put back together as well as the manufacturer part numbers for things you may need to replace like diaphragms, various other seals, solenoids, etc.
I hope this helps.
