Vapor Recovery Vent Valve

Description

Vapor recovery vent valve is installed on the manhole cover of tank truck, the vapor recovery vent connected with vapor recovery pipeline by hose. It is used for vapor recovering in the process of loading or unloading petroleum.

When the tank truck is loading and unloading fuel, poppet valve will be opened by pneumatic controller. Air vapor vent valve maintains oil and gas rapidly flow, recycling, effective seal. it keeps tank pressure balance during oil transportation.

Air-operated sequential vapor valve not only avoid fuel and gas leakage in process of oil transferring, but also prevent spillage in emergency accident.

Air Operated Vapor Valve can be widely installed in 16" or 20" tank manholes. Air Vapor Vent Valve has different seal to suit Diesel, Bio-diesel , Gasoline, Ethanol, Methanol and so on.
