Danfoss SVL Flexline multifunction valve body, SVL 25 straightway socket weld, 25 mm (1 in), 52 bar, steel (code 148B5457)

Danfoss SVL 25 multifunction valve body for the SVL Flexline industrial-refrigeration range, code 148B5457. This is the bare valve housing (body only, without function module) in a low-temperature steel casting; it is welded or threaded 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). Keeping a common body across functions lets a plant standardise on one housing and change the valve duty later. This SKU is the straightway body with 25 mm (1 in) socket weld connections. 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 the inlet and outlet in line; socket-weld ends accept the pipe stub for socket welding (ASME B 16.11). Order the matching SVL function module separately for the required duty and nominal size.

Compatibility

Danfoss SVL Flexline multifunction valve body. Select by nominal size (25 mm / 1 in), body direction (straightway) and connection (socket weld). The same body accepts any SVL Flexline function module of the matching size, so the valve duty (shut-off / regulating / check & stop / check) is set by the top part fitted, not by the body. Butt-weld, socket-weld and NPT-threaded housings are separate codes and are not interchangeable; EN (DIN) and ASME variants are also separate codes — confirm the mating pipe standard before ordering. Straightway and angleway bodies of the same size share the function-module range.
