Compatibility

Danfoss SVL Flexline FIA 50 function module. Mounts on the matching FIA 50 valve housing / SVL 50 multifunction valve body. Pair with a FIA INS strainer insert in the required micron rating (38/72/100/150/250/500). Function modules are size-specific — confirm the housing nominal size (50 mm (2 in)) before ordering. Shares the SVL Flexline platform with SVA-S/SVA-L shut-off, REG regulating and the other check/strainer components of the same size.
