Product Description
Danfoss SVA-S 15 hand-operated shut-off (stop) valve for the SVL Flexline industrial-refrigeration range, code 148B5235. The SVA-S is the standard (short) globe-pattern stop valve used to isolate sections of refrigeration plant for service; it seals bubble-tight when closed and gives full bore when open. This SKU is the straightway body in 15 mm (1/2 in) npt connections to ANSI/ASME B1.20.1. Flow coefficient Kv 6 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 cap/seal 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. Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.

Compatibility & Fitment
Danfoss SVL Flexline SVA-S shut-off valve. Select by nominal size (15 mm / 1/2 in), body direction (straightway) and connection standard (ANSI/ASME B1.20.1 npt). The SVA-S 15 npt/straightway family carries several distinct Danfoss code numbers (each with its own EAN) covering the available cap/seal configurations — order by the exact code for an exact match. SVA-S is the standard (short) body; for the long face-to-face version select SVA-L. Connection preparations (EN 10220 / ASME B 36.10M / ASME B 16.11 / NPT) are not interchangeable — confirm the mating connection. Shares the SVL Flexline platform; the complete top part is interchangeable.
