Solenoid Valve (SV-1)
This 24VDC powered, normally-closed (NC), solenoid valve has push-fit tubing input and outputs designed for standard 1/4" RO tubing. The electrical connection on this solenoid valve fits the DC24 accessory ports found on the Neptune Systems FMM (Flow Monitoring Module), 1Link, and Energy Bar 832 products.1

Common uses include:
  • Shut off for RO and RO/DI systems
  • Emergency shut off for ATO
  • Calcium reactors
  • Planted aquarium CO2 regulation
  • Or anywhere on/off flow of Reverse Osmosis water, RO/DI water, air, or Carbon Dioxide is required.2

The solenoid valve can also be used standalone with a 24VDC power supply (Sold Separately) if you do not own and want to use this solenoid valve with your Energy       Bar 4 or 8.
The Solenoid is not recommended to be used directly with saltwater. Use of a check valve may be necessary to prevent salt water from entering the Solenoid Valve.

Yes, I would recommend this.


Pros: Long cord, great price, reliable brand

Cons: The casing seems to be lacking the higher quality neptune usually provides. A small piece on the bottom keeps falling off.

This is exactly what I was looking for! Used it in conjunction with the FMM module to top off my tank. Easy to install. There is no instructions what so every, but anyone should be able to figure it out.
