Operation: Aerate when draining
The cone is pressed continually into the profile seal by the spring and only opens when there is a negative pressure in the pipeline or the tank.
The 595 valve allows the required volume of air to flow, thus equalizing the pressure and preventing negative pressure and the associated damages from occuring. Subsequently, the valve closes again by spring force.
Valve closed by spring force
Draining produces a negative pressure
Valve opens, air flows in Valve closes after pressure has been equalized
