Flame Arresters & Storage Tank Valves

ERGIL Storagetech™ Model 102 Pressure-Vacuum Relief Valve with Integrated End-of-line Flame Arrester provides total security of mind to operators of storage tanks. The Model 102 ensures protection against damage through over-pressurisation, implosion due to vacuum conditions, and prevents any external �ame entering the tank.

In the closed position the pressure relief pallet and diaphragm assembly is held tightly against a seal to prevent the loss of vapour to atmosphere. As the internal pressure in the tank increases, due to product �lling and vapour development, the pressure in tank increases and in the event that the set pressure of the unit is reached, the diaphragm will open and discharge the gas to atmosphere. The opening set-point is selectable from a range between 1 and 28.1 W.C. (2.5 and 70 mbar), and the valve will reseal when the tank returns to a safe pressure.

The vacuum pallet and diaphragm assembly is similarly maintained in the closed position. As the internal pres-sure in the tank reduces, due to emptying, the balance between the tank pressure and the external atmospheric pressure changes, and when the set pressure of the unit is reached, the diaphragm opens to admit air and rebal-ance the internal pressure. The vacuum set-point is selectable from a range between 1 and 28.1 W.C. (2.5 and 70 mbar). The valve will reseal when the tank returns to a safe pressure.

Unlike the conventional PVRV, the Model 102 discharges vapour and takes in air through the same vent, conse-quently a single end-of-line �ame arrester provides protection from the potential ingress of �ames emanating from an external �re.

Product Description

Flame Arresters & Storage Tank Valves

o o

The integral de�agration �ame arrestor is designed to minimise pressure loss and with an element constructed with a <0.65mm Maximum Experimental Safe Gap is suitable for gas groups IIB and IIA.

Several features are inherent in the valve design to ensure a smooth, positive and e�ective operation. The body is self-draining and drip design prevents condensate from settling on seating surfaces. A diaphragm and seal manufactured from Te�on reduce the possibility of ice formation and sticky residues hindering the valve open-ing, while the pallet assembly moves freely on its guide post.
