CO₂ pressure relief valve for aquaristic purposes: with two pressure gauges and precision adjusting valve. This fitting is necessary, if carbon dioxide is taken from a pressure tank. The vapor pressure of carbon dioxid is about 60 bar and is reduced by the relief valve to 1-2 bars. The needed CO₂ volume is adjusted with the precision adjusting valve. - Because the carbon dioxid is fluid the tank pressure will not fall the first time; not before the CO₂ is nearly finished the tank pressure will fall.

CO₂ is used for chalk reactors (lime reactors) and carbon dioxid reactors.

CO₂ is more heavy than air and may accumulate at the floor - suffocation hazard! Use it only in well aerated rooms.CO₂ tanks are highly pressurized - never open the tank valve without connected pressure relief valve.
