Perfect for controlling your RODI system, top off system, calcium reactor, or other low flow items that use 1/4" tubing. The solenoid valves uses the 24V accessory port found on 1Link modules and the EnergyBar 832.


Solenoid Valve (SV-1)

This 24VDC powered, normally-closed (NC), solenoid valve has push-fit tubing input and outputs designed for standard 1/4″ tubing. The electrical connection on this solenoid valve fits the DC24 accessory ports found on the FMM, 1Link, and Energy Bar 832 products. Common uses include safety stops for RODI systems, CO2 systems on calcium reactors, and many other places where you want to control the on/off flow of water, air, or other gasses. 


Adapting soft 1/4" tubing can be done easily with a 1/4" stem x 1/4" barb adapter.


This solenoid valve can also be used with our standalone 24VDC power supply (not included) if you do not own one of the above products and want to use this solenoid valve with your Energy Bar 8 or Energy Bar 4.

Product Questions

What is the maximum pressure allowed? I want to use this on the line coming into my RODI but just want to make sure I understand what pressure this solenoid can handle.
Question by: Cory Kruip on Feb 12, 2023, 6:23 PM
This solenoid is rated up to 85PSI.
Answer by: William Reed (BRS Staff) on Mar 16, 2023, 10:14 AM
I am using this valve to fill my top off water being supplied from the RO water from the house main with pressure of 50-60psi. It worked for a short time but now in over fills tank and can not turn off water all the way. Is this the wrong application for this device? Is there away to reduce the pressure after the RO system?
Question by: Donn Botzum on Jan 4, 2022, 9:22 PM
You can use a valve and an associated pump with an additional float from a remote water storage tank to a localized ATO reservoir near the aquarium. Having a pressurized RO tube to the display aquarium can lead to desalinization if a failure occurs. It is recommended to have an ATO container at the aquariums location that would not desalinate the aquarium if an ato failure would occur.

Hi, can you use a series of these valves on one single Neptune Dos to dose solutions or two part while also still being able to control auto water changes from the same Dos? Essentially using the valves to open one line, while closing another line to divert the flow from one source or another.
Question by: Justin on Oct 17, 2019, 12:25 AM
Hey there!

Thank you for reaching out to us! In theory you would be able to do this but there is an extremely high level of risk involved. First, you will be putting two part into the lines when a water change is performed. Also, if for some reason a solenoid failed you could potentially use two part for the water change instead of saltwater. We really do not recommend this set up.

I'm trying to incorporate automatic water changes with my Red Sea 525XL using a DoS. Is this something I can use to stop the ATO temporarily while the DoS is swapping water over the course of the night?
Question by: Joshua Facteau on Dec 7, 2018, 11:18 AM
Hi Joshua,

Thanks for reaching out.

As long as you are adding new water to the system at the same rate you are removing old water your ATO should not engage.
If you are using a float valve connected to Red Sea top-off container this would provide an additional level of safety should your clean water reservoir ever empty prior to the water change cycle ending provided you catch it before the solenoid valve opens again.

I hope this helps!
Answer by: Nick on Dec 12, 2018, 11:35 AM
So, if I have an ATO reservoir that's directly connected to my RODI (via float valve), could I insert this between the two to open the flow via fusion/app, filling the bucket? Just using the float valve, I'm finding that the constant trickle of water is rapidly depleting my DI resin.
Question by: Bryan Mack on Jan 15, 2018, 10:56 AM
You definitely could use it for that. I would keep the float valve in place, as a backup, but you could also get two float switches and a breakout box to automate the task completely. Placing one float sensor at the bottom of the reservoir to tell the solenoid to open, and one at the top to tell it when to shut off, with a float valve back up sounds like a pretty sweet setup.

can i add to the length of cable?

Thanks for contacting BRS!

How would you incorporate the 24V power supply? It looks as if the power supply is internal to the solenoid valve.
Question by: Kermeth Huckleberry on Jun 2, 2017, 8:54 AM
Power for the solenoid is designed to be provided through the 1Link accessory plug which the solenoid will plug into through an appropriate module such as the FMM, 1Link, or EB832 power supply. For the FMM and 1Link, a 24v power supply will be plugged into the module.

Have a great day!

Is this valve compatible with salt water or does it require RODI only?
Question by: Dr Salomon on Mar 27, 2017, 10:26 AM
Hey there,
I'm afraid the internal magnetic piston of this solenoid is exposed to the water flow, and as a result it would not be wise to use in a saltwater application. This would be best used for RODI water only, or gas applications.

Have a great day!

What are the measurements and how long is the cable?
Question by: Tom Duncan on Feb 26, 2017, 8:08 AM
Hey There,
The solenoid measures 2.4" x 2.5" and has a 13 ft. cord. If you have any other questions, let us know!
