Product Description
Danfoss SVL 20 multifunction valve body for the SVL Flexline industrial-refrigeration range, code 148B5353. 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 any SVL Flexline function — shut-off (SVA-S/SVA-L), regulating (REG-SA/REG-SB), check & stop (SCA-X) or check (CHV-X) — by fitting the corresponding function module (complete top part). This SKU is the straightway body with 20 mm (3/4 in) butt weld connections to EN 10220. Bi-flow body; maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F). Steel construction suits HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) systems. Straightway bodies place inlet and outlet in-line. Order the matching SVL function module separately for the required duty and nominal size.

Compatibility & Fitment
Danfoss SVL Flexline multifunction valve body. Select by nominal size (20 mm / 3/4 in), body direction (straightway) and connection (butt weld EN 10220). The same welded body accepts any SVL Flexline function module of the matching size, so the valve duty is set by the top part fitted, not by the body. EN 10220 and ASME weld-end variants are separate codes — confirm the mating pipe standard before ordering.
