Vapor Vent Valve

Vapor vent valve on a fuel tank is designed to release vapors that accumulate in the space above the liquid level in the tank. Fuel tanks store volatile and flammable liquids such as gasoline, diesel, and jet fuel, which can release vapors that are hazardous to workers and the environment if not properly vented.

Vapor vent valve is typically located on the top of the tank and is designed to allow for the release of vapors during filling and emptying operations. It also serves as a safety feature to prevent the accumulation of explosive gases inside the tank.

Vapor vent valve on a fuel tank typically consists of a vent pipe that extends from the top of the tank to the outside of the tank, allowing vapors to be released to the atmosphere. Additionally, the vapor vent may be equipped with a flame arrestor, which prevents any external flames from entering the tank and igniting the flammable vapors inside. This is an important safety feature that helps to prevent accidents and protect workers and the environment.

Vapor relief valve is designed for bulk transport trucks.

If a system blockage were to occur, the valves are designed to open to atmosphere to prevent the tank from imploding.
