Neptune Systems SV-1 Solenoid Valve

Neptune Systems Solenoid Valve – Reliable Aquarium Solenoid Valve for Automation

The Neptune Systems Solenoid Valve (SV-1) expands Apex automation by controlling RODI systems, calcium reactors, and top-off lines with precision. Built by Neptune Systems, this water solenoid valve belongs to the Automate and Monitor category, giving aquarists a dependable solution for flow control in reef systems.

Why the Neptune Systems Solenoid Valve Fits Controllers

This aquarium solenoid valve integrates directly with Apex Controllers, while also extending functionality into Water Level, Controller Accessories, Evaporation Control, and Flood Control and Leak Sensors.. Because it plugs into DC24 accessory ports on the FMM, 1Link, and Energy Bar 832, it simplifies setup while ensuring reliable automation. In addition, the push-fit connectors allow quick attachment to standard 1/4-inch tubing.

Key Features of the Neptune Systems Solenoid Valve

• Provides 24VDC power in a normally closed (NC) design

• Connects with push-fit ends for standard 1/4-inch tubing

• Works with FMM, 1Link, and EB832 accessory ports

• Controls RODI, calcium reactors, CO₂ systems, and more

• Operates with an optional standalone 24VDC power supply (sold separately)

Practical Applications for the Aquarium Solenoid Valve

Use the Solenoid Valve to add precise control wherever you need on/off flow. For example, it stops RODI water production at the right time, prevents accidental overfilling in ATO systems, or regulates CO₂ flow in calcium reactors. Moreover, it adapts easily to soft tubing with a 1/4-inch stem × 1/4-inch barb adapter, so integration remains simple and flexible.
