The Cashco 1078 nitrogen tank blanketing valve is a pilot-operated valve, specifically designed to eliminate the oxygen and moisture from the vapour space above your stored product, protecting sensitive and valuable media from evaporation, moisture ingress, contamination, oxidation and evaporation.

If the media is combustible, the nitrogen blanketing eliminates the oxygen, preventing combustion. With the oxygen eliminated, moisture cannot be drawn into the tanks causing internal corrosion, thereby protecting the tank, maintaining integrity and extending it’s life.

When vapour recovery systems are installed together with Cashco nitrogen tank blanketing valves, harmful vapors are also prevented from entering the atmosphere.

It opens and closes automatically as required, to maintain a closely controlled blanket pressure. The simple design, increases reliability and lowers maintenance cost and allows tanks to be controlled with much tighter tolerances than before. The unit has multiple flow plugs, sensing configurations, and body configurations in order to meet the specific needs of the end user.

Applications

Primarily used in the Chemical, Petrochemical and Oil & Gas Industries.

On many low-pressure storage tanks the operating range is very low, which makes blanketing and venting system selection/design a challenge for the engineer. The Vacu-Gard® makes the job much easier. First, the Vacu-Gard® set point definition is where the blanketing valve closes bubble tight.

This gives the largest dead band between the blanketing valve set point and the set point of the relieving device, and therefore will reduce losses. Second, the Vacu-Gard® has a wide range of available settings, from vacuum to 0.96 Barg, that make proper selection easier.

We have full valve repair and reconditioning facilities in Secunda & Durban.
