Product Description
Danfoss SVL 25 multifunction valve body for the SVL Flexline industrial-refrigeration range, code 148B6644. 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 straightway body with 25 mm (1 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 & Fitment
Danfoss SVL Flexline multifunction valve body. Select by nominal size (25 mm / 1 in), body direction (straightway) 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.
