Danfoss SVL Flexline multifunction valve body, SVL 25 angleway NPT threaded, 25 mm (1 in), 52 bar, steel (code 148B5458)

Danfoss SVL 25 multifunction valve body for the SVL Flexline industrial-refrigeration range, code 148B5458. 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 angleway body with 25 mm (1 in) NPT threaded 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. Angleway bodies place the inlet and outlet at 90 degrees; NPT female-threaded ends mate to NPT pipe (ANSI/ASME B1.20.1). 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 (angleway) and connection (NPT threaded). 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.
