Inverse Pressure Relief Valve

This valve is used in the area of fan control. With the help of increasing current flow, the pressure in the system can be reduced and, as a result, the fan speed can be continuously regulated. As a result, it is ensured that even in the event of a defect, there is sufficient cooling by the ventilation system. Furthermore, the valve guarantees a low differential pressure at maximum flow and ensures energy efficiency.
