1-body; 2-flame arrester; 3-adapter; 4-vacuum valve; 5-pressure control valve; 6-cover; 7-casing.
Combination (nonfreezing) breather valves in accord with TU U 29.124607422-016-2001 are intended for sealing of gas space in the tanks with oil and oil products for protecting it from the environmental impacts and maintaining of pressure in this space within specified limits, as well as elimination of occurrence of sparks and flame inside the tank.
