Siphon protection
Siphon protection valves or angle check valves are prescribed safety devices for heating oil tank systems.
In tank installations where the highest liquid level is above the suction line, there is a risk of siphoning. If there is any leak or leakage in the suction lines, the tank contents may run dry without siphon protection.
Siphon protection valves prevent the liquid from leaking at this point.
Siphon protection tested according to:
E DIN EN 12514-3:2009-06
