Manufacturer: Aquarium Gardening

Product Ref: 5500/8493643
CO2 Needle Valve Needle Valves are used for precision control of the flow of CO2 gas, which is not possible by use of the regulator alone. The bubbles should be fine tuned so that they are VERY SMALL and rise slowly and lazily to the top of tank, but become absorbed finally about 1-2 inches before reaching the surface. This way maximum use of the CO2 gas is achieved. This Aquarium Landscapes Needle Valve is manufactured to the highest standards possible, as it is used also for control of gases in the medical profession. The unit is a subminiature precision needle valve, for sensitive and repeatable control of liquids, air, and gases. Each unit is designed for use with a maximum flow equal to a CV of .09 and a maximum pressure of 125 PSI. The Needle Valve can give precise control of CO2 gas when installed as directed, thus enabling the optimum use of CO2 gas in the aquarium.
