Compatibility

Danfoss SVA-S Flexline shut-off valve, socket-weld / NPT connection variant. Select by nominal size (DN20 / 3/4 in), body direction (angleway) and operator (hand wheel). Socket-weld/NPT, butt-weld and solder bodies are separate codes and are not interchangeable — confirm the mating pipe connection before ordering. Function modules and spare/overhaul kits are shared across SVA-S bodies of the same size.
