Quick Overview

Use the Water Valve 8555.200 from Tunze to connect to the Tunze Osmolator - the water valve replaces the pump with an electrically operated solenoid. Use it to control the flow of water from a tube rather than pumping it from a container like gravity-fed auto top off system.

Will the Tunze water valve work with the Tunze Osmolator Nano 3152?
Question by: Caleb on Jun 8, 2014 1:43:00 PM
Hi Caleb,
Unfortunately the Osmolator accessories (switch socket, water valve, etc) are only made to work with the Osmolator 3155.
Answer by: Bulk Reef Supply on Jun 8, 2014 1:43:00 PM
Is it possible to run two of these off the same Osmolator? My thought here is that my sump is going to cost me around $900 and I'm quite worried about drilling a hole in it for a float valve as a secondary shutoff. But if I could run two of these... even if one failed in the on position the second should run properly and stop flow.

Is this a sound plan?

Thanks,
Brian

Great question!
These will not be able to run 2 on 1 osmolator. the voltage would vary for each causing them to not function. individual controller will be required for each water valve. Feel free to let us know if you have any further questions!

Does this solenoid just use 110v power? Can I use it with a timer plugged into a wall outlet or would I need to buy the tunze controller also? Thanks
Question by: Chad on Jan 21, 2016 1:19:00 PM
Great question,
This solenoid is connected directly to the Tunze Osmolator controller and does not have a rating on what voltage would work. Feel free to let us know if you have any further questions!

When the power fails, does this valve close?
Question by: Mike on Jan 20, 2014 8:07:00 AM
Hi Mike,
This is a normally closed valve, so unless it is being powered then the valve is closed.

  • Problems By Turk on 3/7/2016

    Nice when works properly but it will not open half the time when it should and tunze unit shuts down; I then have to reset tunze each time after unplugging power to it
  • Failed in the on position. Scary stuff. By Angelo on 2/1/2016

    Recommend (sort of)with big caveat. Used without issue for 6 months. BRS video on redundancy for Tunze osmolator and RO/DI saved me big time. Big time. Solenoid stuck on the on position and fortunately float killed flow. Apex shut everything down but didn't matter as solenoid was open

    Event has left me not trusting it completely. I will switch to pump that apex can shut down.

    Changing resin probably left a bit to go downstream and contibuted to failure of gate. BE CAREFUL WHEN CHANGING RESIN

  • No more carrying RODI water By jsbull on 1/2/2016

    I love this thing. It allowed me to use my Tunze ATO system along with an RODI installed in the room behind my tank. I just run the blue line through the wall and it's all set. I never have to carry RODI water again!

    Pro tip: I have a reservoir above my sump that has a mechanical float valve. It simply gravity feeds into the sump as the water level drops. Therefore, the RODI and Tunze just refill this reservoir. So, I programmed my Apex to only power the ATO for 60 minutes, 1 time per day. This lets it keep the reservoir full, but doesn't cause the creep in my RODI system that you get when it does short cycles.
  • Broke while unpacking By Reefing Apprentice on 11/24/2015

    I was in the process of setting up my new valve when a plastic fitting broke off from the brass value. Very disappointed, because now I'm working on returning the until to the manufacturer instead of working on my reef project.
  • Awesome valve By grhoades on 2/12/2015

    The way the valve is built inspires confidence! I just connected it last night and already am very happy...no leaks and no mess. Long cable with soldered ends is a big help too.
  • Works fine and as described By Eddie on 9/5/2014

    I needed this valve to replace my pump because I was tired of filling my top off container every 3 days. I set up another RO/DI to automate this process and I'm using this valve. I added a float valve in the sump to prevent any floods if the valve fails (of course it should fail in off position according to the instructions). Also, I added a float switch and set it to turn off the ATO through my apex neptune. I don't know if it's overkill but I'm paranoid about having a flood. It's been working great so far and the push connectors don't leak. There may be cheaper alternative I imagine but I did not want to spend the extra time and effort. Overall a great product if you want to hook up your RO/DI unit up for ATOs
