To adjust the flow rate of the differential control on the 41AF rate of flow control valve, which direction should the adjustment screws be turned?

Turning the adjustment screws counterclockwise to achieve minimum spring tension is the correct approach when adjusting the flow rate of the differential control on the 41AF rate of flow control valve. This is because reducing the spring tension allows the valve to respond more freely to changes in flow rate, effectively decreasing the resistance against which the flow must work.

When spring tension is minimized, the valve will open more easily, permitting a higher flow rate, while also allowing for finer control over the flow adjustment. This action can help achieve the desired flow rate without overloading the system, ensuring efficient operation. It is essential in systems where precision in flow management is critical.
