Honeywell 40003916-003 V4073A

The 40003916 power heads enable the complete power head assembly to be replaced, without draining down, on V4043C and V4043H Zone Valves.

On older style valves, which did not have the replaceable head feature, the adaptor plate assembly can be used to upgrade the valves to allow the replaceable power head to be used.
