OPV – Overfill protection valve.
An overfill protection valve (OPV) is a safety device installed on fuel tanks to prevent overfilling. It is designed to automatically shut off the fuel flow into the tank when the fuel level reaches a certain point.
The OPV uses a float mechanism that rises with the fuel level in the tank. When the fuel level reaches a predetermined level, the float triggers a valve to shut off the fuel flow. This prevents the tank from overfilling and spilling fuel, which can be a fire hazard and environmental risk.
OPVs are commonly used in both above-ground and underground fuel storage tanks, such as those used for gasoline, diesel, and other petroleum products. In many jurisdictions, they are legally required to handle these hazardous materials safely.
In addition to the float mechanism, an OPV typically includes various other safety features, such as a pressure relief valve and a venting system. These features help to prevent the tank from becoming over-pressurized and ensure that any vapours released during fueling are properly vented to prevent explosions and other hazards.
Overall, the OPV is an essential safety feature for fuel tanks, helping to prevent accidents and protect people and the environment from the risks associated with fuel spills and overfilling.
Flame arrestor, Vent and Desiccant breather
Flame Arrestor:
A flame arrestor is a safety device that prevents flame propagation from an external source to a flammable gas or vapour in a pipeline or storage tank. It provides a narrow passageway with metal plates or screens that can cool down and extinguish flames while allowing gas or vapour flow to continue.
Vent:
A vent is a device used to release pressure and/or prevent the buildup of a vacuum in a storage tank or vessel. Vents are designed to protect the tank or vessel from damage due to overpressure or vacuum and to prevent explosions or implosions that may occur if the tank or vessel is not vented correctly.
Desiccant Breather:
A desiccant breather is a device that removes moisture and particulate matter from the air entering a storage tank or other sealed vessel. It is used to protect the contents of the tank or vessel from contamination by moisture and particulates, which can cause corrosion and other problems. Desiccant breathers typically contain a desiccant material, such as silica gel, that absorbs moisture from the air passing through the breather
