The HYDROS DC Solenoid Valve is a handy HYDROS Control 2 and Control 4 accessory that provides easy on/off RO or RO/DI water flow. You can connect the solenoid to your reverse osmosis filter and use it to top-off your tank if you don't have the room available for a separate ATO reservoir.

The HYDROS DC Solenoid Valve works in conjunction with a HYDROS aquarium controller and an optical or mechanical water level sensor. When the sensor detects the water level is low, it opens the valve to allow fresh RO or RO/DI water to flow through and top-off your tank or sump. When the sensor senses that the water level is replenished, it will tell the Control 2 or Control 4 to shut off power to the solenoid. This closes the valve to stop the flow of reverse osmosis water. The HYDROS DC Solenoid Valve should be connected to the product line coming off your reverse osmosis system. It has 1/4" push-connect fittings to insert standard RO tubing quickly and easily.

Instead of using the HYDROS DC Micro Pump as your ATO pump, you can use the HYDROS DC Solenoid Valve instead. Just plug it into a Drive Port on the Control 2 or Control 4 for power and control and configure in the HYDROS app. It is recommended to install an auto-shutoff valve and check valve on your reverse osmosis system to prevent it from producing wastewater when the solenoid is closed.

The HYDROS DC Solenoid Valve is an Official HYDROS Accessory manufactured by AutoAqua in Taiwan. Creators of the Smart ATO Micro, AutoAqua is one of the most well-known and trusted makers of ATO systems in the aquarium hobby today. CoralVue has thoroughly tested the DC Solenoid Valve to ensure seamless compatibility with the HYDROS platform. The product development team at CoralVue engineered the solenoid so it connects with a Drive Port on the controller using an aviation-style plug for safer operation. No additional power source is needed to run the solenoid.
