The RegO A3186<\/strong> is a back pressure check valve, also known as a non-return valve. Its primary function is to prevent gas backflow, which can cause system failures and compromise safety.<\/p>\n

How it works:<\/strong><\/h5>\n

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