Backflow prevention valves

Backflow prevention valves

Durgo has a wide range of vacuum valves that are designed to prevent syphon and overpressure backflow. They are available in several types and dimensions. Many are classed in accordance with the EN 1717
standard, others are the more traditional horizontal or vertical terminal types. Our vacuum valves are of the high pressure type and can be fitted straight on to the hot and cold mains.
