Our QDVA16 Float Operated Drain Valve is a universal replacement for most Manufacturer's
Filter Housings float type drain. This Normally Closed drain is Automatic, which operates when the float rises due to accumulated liquid, discharging condensate and debris from within the filter bowl.

Automatic Drains should be used where the filter location may make servicing difficult, where filters may be hidden from view and consequently overlooked, or where equipment is in continual use. Areas where large quantities of liquid may accumulate over a short period of time should be equipped with an auto-drain.
