Compatibility

Danfoss SVL Flexline SVA-L stop valve. This code is the straightway SVA-L 25 with socket weld (ASME B 16.11) ends and a handwheel. Confirm line size (25 mm / 1 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.
