The RegO 3146<\/strong> is a check valve, also known as a non-return valve, whose main function is to prevent gas backflow, which can cause system failures and compromise safety.<\/p>\n

How the RegO 3146 valve works:<\/strong><\/h5>\n

The Back Pressure Check Valves allows gas to flow freely in one direction, but blocks gas return in the opposite direction. When gas attempts to flow back through the system, a disc or piston inside the valve closes automatically due to reverse pressure, preventing backflow. This mechanism is activated by the pressure differential between the two ends of the valve. <\/p>\n
