1078 – Cashco tank blanketing valve
Balanced pilot, 100% verified setpoint
The Model 1078 Vacu-Gard is a pilot-operated valve, specifically designed to reduce blanketing gas losses on low pressure storage tanks. It opens and closes automatically as required, due to emptying of tank and thermal inbreathing, to maintain a closely controlled gas blanket pressure allowing tank pressures to be controlled at much tighter tolerances than with standard regulator. It is intended for installation on top of the medium or large storage tanks. The simple design, increases reliability and lowers maintenance cost. With multiple body materials, soft good seals and the performance that is unmatched in the industry, the Model 1078 is the clear choice.

Tank blanketing, also referred to as tank padding or make up, is the process of applying blanket of an inert gas (nitrogen) in the vapour space above the liquid in a closed storage tank. Inert gas blanketing valve works as primary vacuum relief. The inert gas is supplied at a required pressure during pump off or thermal contraction events in order to prevent air and moisture from entering into the tank and thus control and prevent the fire. The other common names for N2 Blanketing valve are Inert gas blanketing valve and low pressure reducing valve.
