01
What is an LPG cylinder valve?
−It is the brass fitting screwed into the neck of an LPG cylinder. It seals the gas in, lets the cylinder be filled and emptied safely, and connects the cylinder to the regulator or appliance. Many valves also carry a pressure-relief valve that vents gas if pressure inside the cylinder climbs too high.
