Vacuum and Pressure Valve

Vent Terminal equipped with a dual function valve that, in the normally closed position, prevents vapor discharge through the vent pipe into the environment, thus allowing for operation economy.When there is a variation in the inner pressure of the Storage Tank generated by the Fill operation (opening minimum pressure = 0.12 psi), or Delivery operation (minimum opening negative pressure = 0.06 psi), the valve operates and releases the Vent Pipe.Its design directs the gas exit upwards minimizing the accumulation of gases in the Station perimeter. The valve is also used in Vapor Recovery Systems.
