Danfoss SVA-L 15 straightway long shut-off (stop) valve, 15 mm (1/2 in) butt weld EN 10220, 52 bar, steel (code 148B5251)
Danfoss · HVAC & Refrigeration · Globe Valves
Danfoss SVA-L 15 hand-operated shut-off (stop) valve, long version, for the SVL Flexline industrial-refrigeration range, code 148B5251. The SVA-L shares the SVA-S valve function — a globe-pattern hand stop valve that isolates sections of plant for service — but has a longer face-to-face length, allowing direct replacement of older long-pattern valves and giving extra spindle clearance. This SKU is the straightway body in 15 mm (1/2 in) butt-weld connections to EN 10220. Flow coefficient Kv 4.9 m3/h. Steel housing rated 52 bar (754 psig) maximum working pressure, media temperature -60 to 150 C (-76 to 302 F). Back-seating spindle allows the seal cap to be serviced under pressure; a vented seal cap can be exchanged for a hand wheel. Suits HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) systems. Built on the SVL Flexline modular platform — the complete top part is interchangeable across the SVA-S/SVA-L, REG, SCA-X and FIA functions.

Compatibility
Danfoss SVL Flexline SVA-L (long) shut-off valve. Select by nominal size (15 mm / 1/2 in), body (straightway) and connection standard (EN 10220 butt weld). SVA-L is the long face-to-face version of the SVA-S; choose SVA-L where the extra installed length or spindle clearance is needed, otherwise the standard SVA-S. Connection preparations (EN 10220 / ASME) are not interchangeable — confirm the mating pipe schedule. Shares the SVL Flexline platform; the complete top part is interchangeable across functions.
