Our tank gas blanketing valve, the Vacu-Gard®, is the result of over 30 years experience with tank nitrogen gas blanketing valves and has been designed specifically for tank blanketing applications.
The model 1078 is a pilot-operated valve, specifically designed to reduce blanketing gas losses on low pressure storage tanks. It opens and closes automatically as required, to maintain a closely controlled blanket pressure. The simple design, increases reliability and lowers maintenance cost.
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 14 psig, that make proper selection easier.
