Danfoss SVL 6 multifunction valve body (SVL Flexline), angleway, 6 mm (1/4 in) butt weld EN 10220, steel, 65 bar (code 148B6689)

Danfoss SVL 6 multifunction valve body for the SVL Flexline industrial-refrigeration range, code 148B6689. This is the bare valve housing (body only, without function module) in a low-temperature steel casting; it is welded permanently into the line and then converted to a shut-off (SVA-S / SVA-L), regulating (REG-SA / REG-SB), stop & check (SCA-X) or check (CHV-X) valve by fitting the matching SVL Flexline function module (complete top part). Standardising on one welded housing lets the valve duty be changed later without re-welding. This SKU is the angleway body with 6 mm (1/4 in) butt weld connections to EN 10220. Bi-flow body; maximum working pressure 65 bar (943 psig); media temperature range -60 to 150 C. Steel construction suits HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) systems. Order the matching SVL function module separately for the required duty.

Compatibility

Danfoss SVL Flexline multifunction valve body. Select by nominal size (6 mm / 1/4 in), body direction (angleway) and connection standard (EN 10220 butt weld). The same welded body accepts any SVL Flexline function module of the matching size, so the valve duty (shut-off / regulating / stop & check / check) is set by the top part fitted, not by the body. EN (DIN) and ASME weld-end variants are separate codes — confirm the mating pipe standard before ordering. Angleway and straightway bodies of the same size share the function-module range.
