1078 Vacu-Gard Tank Blanketing Valve

The 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.

The 1078 valve 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.

The 1078 valve has a wide range of available settings, from vacuum to 14 psig, that make proper selection easier.

Top entry Design that is compact and lightweight, yet allows complete access to the valve internals without being removed from the tank.

The only time the diaphragm case needs to be disassembled is when replacing the diaphragm. Increased stability with a pressure balanced pilot.

Fluctuations in supply pressure does not affect set point. Valve set point can be verified 100% on the tank, without removal and without flowing supply gas into the tank. Temperature changes have no appreciable effect on set point Shutoff: Bubble tight at set point, prevents waste of blanketing gases.

Easy Maintenance:

Uses standard O-rings for seat and seals.
