Vetus ASDV - Anti Syphon Device with valve, 13 - 32 mm Bernard Inspection coverType ASDV air vents are interchangeable with type AIRVENT and have the same fixing hole centers. The advantage is that the air bleed connection rotates through 360. In addition, the valve can be maintained without removing the vent from the wall and no tools are required to do this. For replacement, a set with 5 valves is available as a spare part.
