The diaphragm anti-siphon valve is installed into the suction line of oil-fired heating systems according to DIN 4755, where the maximum tank filling point is located at a higher level than the lowest point in the suction line.
The valve prevents heating oil from being siphoned out of the tank in case of a possible leakage in the following suction line. Installation is possible in the suction line of single-pipe systems as well as in dual-pipe systems. In dual-pipe systems the return feed has to end with a free outlet in the tank.
General type approval by DIBt Z-65.50-305.
