Compatibility

Danfoss SVL Flexline SVA-S SS stop valve. This code is the straightway SVA-S SS 65 with butt weld (EN 10220) ends and a handwheel. Confirm line size (65 mm / 2 1/2 in), connection type/standard, direction (straightway) and refrigerant before ordering. SVA-S and SVA-L share the same internal parts; the difference is neck length only.
