Gas Blanketing

The valves are designed to control a blanket of gas above a stored liquid within a vessel whilst also reducing the blanketing gas losses on low pressure storage vessels. This also reduces the degradation of the stored product by preventing air from entering the vessel. The valve also prevents the collapse of the vessel due to excessive vacuum created when product is pumped out of the vessel.
