R128 tank emergency vent
The R128 emergency vent relieves positive pressure from a storage tank. It has a larger opening than the R102 vacuum relief valve and serves the pressure discharge path rather than the admission of air to compensate for vacuum. The size range is DN400–DN600, or 16–24 inches, with positive settings from 10 to 50 mbar. Carbon steel and 304 or 316 stainless steel body materials are described, with ISO PN10 or Class 150 flanges. State the required size, pressure setting and material in the inquiry.
