Full Title

Full titles differ between systems:

IPC:

Lift valves, i.e. cut-off apparatus with closure members having at least a component of their opening and closing motion perpendicular to the closing faces > with screw-spindle > Special arrangements for improving the flow, e.g. special shape of passages or casings > in which the spindle is inclined to the general direction of flow

CPC:

Lift valves , i.e. cut-off apparatus with closure members having at least a component of their opening and closing motion perpendicular to the closing faces ( ; diaphragm valves F16K7/00) > with screw-spindle (F16K1/12 - F16K1/28 take precedence; actuating mechanisms with screw-spindles F16K31/50) > Special arrangements for improving the flow, e.g. special shape of passages or casings > in which the spindle is inclined to the general direction of flow

No child classifications to compare. This is a leaf node in both IPC and CPC.
