Frequently Asked Questions
Why does Sun use 2 slip orifices?
The divider/combiner is an FSDH XAN. Input flow is 15 gpm (57 L/min.). This example depicts orifices that slip about 3 gpm (12 L/min.) at 3000 psi (210 bar) pressure differential between legs. The slip conditions between the 2 examples are the same...please be assured of this. Each orifice on the right is twice the area of the orifice on the left.
The pressure drop through the left example is 200 psi (14 bar), the drop through the right example is 130 psi (9 bar).
