Description
Wennstrom • End-of-Line pressure/vacuum valve (+20/-4 mbar)
End-of-Line pressure/vacuum valve (+20/-4 mbar) will protect the storage tank from damage due to pressure by balancing pressure tops and drops.
Containment
Under normal operating conditions, tanks containing petroleum products should be sealed to the atmosphere. This not only minimizes the spreading of VOC vapours, it also prevents unnecessary ventilation which may lead to damp air condensating into water in the tank.
Protect the storage tank
A pressure/vacuum valve will protect the storage tank from damage due to pressure by balancing pressure tops and drops.
The Wennstrom pressure/vacuum valve is based on a patented gravity solution that enables a wide range of pressure and vacuum values, depending on the field of use and the local requirements. The End-of-Line version is constructed to fulfill the leak rate requirements of California standards.
The ease of installation and no requirements of periodical maintenance make the pressure/vacuum vent valve the perfect choice.
Total risk analysis
In combination with a flame arrester (SKU: ES1180CJ and ES1180CJ-2) in the ventilation pipe and the HSE Interlock valve at the filling point, the storage tank will be effectively safeguarded against the probable explosion risk.
