Valken Green Gas is a pressurized gas used to power airsoft gas magazines and gas powered grenades;

Green gas delivers approximately 115 psi at 70-degrees Fahrenheit, and their cans are DOT approved;
They also have an integrated safety valve to release pressure automatically to reduce explosion risk whenever the pressure exceeds a safety level due to temperature or other reasons.
