Product Description
Danfoss REG-SA 25-40 function module (also called Top Complete) for the SVL Flexline modular industrial-refrigeration valve platform, store code 148B5480. The function module is the complete field-serviceable operating top part — top part, one gasket and four bolts — that mounts on the matching REG-SA 25, REG-SA 32 or REG-SA 40 regulating valve housing. A scaled spindle top gives repeatable manual throttling of liquid, suction, hot-gas and oil flow. It is the repair/replacement assembly with cap, not a complete valve and not a loose gasket, so the regulating (throttling) function can be renewed without cutting the housing out of the line. For R717 (ammonia), R744 (CO2) and fluorinated refrigerants and their oils. Maximum working pressure 52 bar (754 psig); media temperature -60 to 150 C (-76 to 302 F). Specifications per Danfoss store code 148B5480.

Compatibility & Fitment
Danfoss SVL Flexline REG-SA 25-40 function module (Top Complete, 52 bar). Mounts on the matching REG-SA 25/32/40 valve housing / SVL multifunction valve body. Function modules are size-specific — confirm the housing nominal size class (25-40) and the 52 bar rating before ordering (a separate 65 bar version exists). Shares the SVL Flexline platform with SVA-S/SVA-L shut-off, REG regulating and SCA-X/CHV-X check components of the same size.
