Compatibility & Fitment
Danfoss SVA-S 6 is a manual stop valve for industrial refrigeration lines. Confirm nominal size (6 mm / 1/4 in), connection standard (butt weld), flow direction (straightway) and operation (cap vs hand wheel) before ordering. SVA-S uses a standard bonnet length; SVA-L is the long-bonnet, insulation-friendly variant. Function module and valve housing are available separately as service parts.
