When the controller calls for water, the valve opens and pressurised RO water flows directly into the tank or sump. It runs on 6 W at 12 V DC taken from the controller's pump socket, joins the line with quarter-inch push-fit RO tubing, and operates on any supply between 0.02 and 0.7 MPa. It suits reef and freshwater keepers who already make their own RO water and want the top-off reservoir out of the cabinet entirely.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRuns off the controller's pump socket\u003c\/strong\u003e — 6 W at 12 V DC through a 5.5 x 2.5 mm plug, so there is no second power supply competing for an outlet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect feed instead of a reservoir\u003c\/strong\u003e — water comes from the pressurised RO line, so there is no drum to refill and no submerged pump sitting in it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuarter-inch push-connect\u003c\/strong\u003e — the same tubing standard as every RO\/DI unit, so it drops into an existing line.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide operating window\u003c\/strong\u003e — 0.02 to 0.7 MPa covers household mains pressure and a gravity-fed drum mounted high enough.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e120 cm valve lead\u003c\/strong\u003e — reaches from a controller in the cabinet to a line entering at the back.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNothing in the water\u003c\/strong\u003e — no impeller to scale up, block or wear out.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e6 W at 12 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower source\u003c\/th\u003e\n\u003ctd\u003eHost AutoAqua controller's pump socket — no separate adaptor supplied\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDC connector\u003c\/th\u003e\n\u003ctd\u003e5.5 x 2.5 mm male\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eValve cable length\u003c\/th\u003e\n\u003ctd\u003e120 cm (4 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking pressure\u003c\/th\u003e\n\u003ctd\u003e0.02 to 0.7 MPa (0.2 to 7 bar)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater connection\u003c\/th\u003e\n\u003ctd\u003eQuarter-inch push-connect RO tubing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater carried\u003c\/th\u003e\n\u003ctd\u003eFiltered RO or RO\/DI water only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eAutoAqua top-off and water-change systems that use a submersible refill pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer part number\u003c\/th\u003e\n\u003ctd\u003eSV-12V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003ch3\u003eFeed pressure — will it open on my line?\u003c\/h3\u003e\n\u003cp\u003eA solenoid valve does not pull water.
