Compatibility

Danfoss SVA-S 25 is a manual stop valve for industrial refrigeration lines. Confirm nominal size (25 mm (1 in)), connection (butt weld to ASME B 36.10M Schedule 80), 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.
