Nominal flow rate measures the volume of liquid passing through a system under specific pressure conditions. Depending on region, the nominal flow rate may be measured in gallons per minute, or GPM, or litres per minute, or LPM. High-volume applications may even be expressed in gallons or litres per second.

For switching directional valves: Flow rate causing a pressure drop of 1 bar when it passes through the valve. » Guide nominal flow rate; Laymen often do not know what exactly the technical terms mean, so we will try our best to explain the terms volume flow, The fan most suitable with the system is chosen by considering not only the flow rate but also power consumption to ensure maximum harmoniousness with the existing system. The volume flow Nominal flow capacity is based on performance limits. Maximum flow capacity is based on pressure drop. When selecting any direct-acting solenoid valve, first check the performance limits plot, then check if pressure drop is acceptable.
