The figure in liters/hour (L/H) is the maximum flow through the valve.

These valves provide a means of externally adjusting the level inside a vessel. They are ideal for use with liquid separators or liquid-liquid extractors. The lower end of the PTFE bellows is in the form of a tube of accurately machined external diameter, which fits inside a precision bore glass tube. Its position can  adjusted within given limits (L3) to set the required overflow level. In applications where the system is nor self venting via the overflow line, a vent line can be connected to the DN15 nozzle.
