Compatibility

Danfoss SVA-L (long neck) shut-off valve for the SVL Flexline industrial-refrigeration range. Select by nominal size, body direction (angleway / straightway), connection (weld standard) and top equipment (handwheel or cap). The SVA-L is the long-neck variant of the SVA family; the manually operated globe valve seats on back-seating and is bi-flow. Butt weld, socket weld and NPT threaded end variants are separate codes and are not interchangeable; EN and ASME weld-end variants are also separate codes — confirm the mating pipe standard before ordering.
