The Brand, BG4 non-adjustable priority flow divider receives a single stream of fluid and divides it into a priority stream and an excess stream. The priority flow port maintains the same flow even with an increase or decrease in the input flow. Both outlet flows are pressure compensating and the sum of said flows equals the inlet flow. Flow can only pass through the valve in one direction, inlet to outlet. Accuracy is normally better than + 5%. The priority flow setting must be specified when ordering. Pressure drop through the valve will range from 33 to 50 psi (2.3 to 3.4 bar) depending on the flow and pressure in the system.
