Compatibility

Danfoss SVA-S SS Flexline stainless hand-wheel shut-off valve. Select by nominal size (DN20 / 3/4 in), body direction (straightway) and operator (hand wheel vs cap). The stainless SS body is a separate code from the carbon-steel SVA-S; SVA-S is standard-neck and SVA-L is long-neck — confirm body material, neck length and pipe connection before ordering.
