Tank Vent Valve

Tank Vent valve, also known as spring-loaded breather valve, oil tank truck breather valve, vent valve, etc., is an essential product on oil tanks such as oil tank trucks, fuel trucks, oil tankers, etc. It can regulate the pressure inside the tank and automatically open and close when pressure is input or discharged into the tank, maintaining a constant pressure inside the tank, reducing the outflow of oil and gas, and keeping the oil clean inside the tank.

Tank Vent valve are mainly installed on the top of the oil tank to ensure the safety of the tank by maintaining the balance of internal and external pressure. The Tank Vent valve also has a splash guard to prevent oil spillage during transportation, achieving energy saving and environmental protection.

Tank vent valve is a device that is installed on a storage tank to regulate the pressure and flow of air into and out of the tank. The valve is typically located on the top of the tank and is designed to allow for the safe release of excess pressure or vacuum that can occur as the temperature or level of material in the tank changes.

The tank vent valve is an important safety feature that helps to prevent the tank from becoming over-pressurized or experiencing a vacuum collapse, which could lead to structural damage or other safety hazards. Additionally, the vent valve helps to prevent the build-up of volatile organic compounds (VOCs) inside the tank, which can be harmful to the environment and human health.

There are different types of tank vent valves, but most operate on a spring-loaded mechanism that opens or closes depending on the pressure inside the tank. Some tank vent valves are equipped with a flame arrestor to prevent the ignition of any flammable vapors that may be present inside the tank.
