Control on/off flow in a compatible aquarium system with the Neptune Systems SV-1 solenoid valve. This electrically operated valve can provide an automated shutoff for RO/DI lines or compatible calcium-reactor CO₂ systems.

• 24V DC powered, normally closed: closes when power is removed.
• Push-fit inlet and outlet for standard ¼-inch tubing.
• Connects to DC24 accessory outputs on the Neptune FMM, 1LINK and Energy Bar 832.

Requirements: Suitable Neptune DC24 power/control connection and appropriate programming. A compatible standalone Neptune 24V DC power supply, sold separately, enables switched operation from an Energy Bar 8 or Energy Bar 4. An FMM requires an appropriate power supply to power its DC24 accessory output.

Includes: SV-1 valve. Controller, module/power supply, sensors, tubing and CO₂ regulator are sold separately. The valve does not detect leaks or water level by itself.
