Description
The Xylem-McDonnell & Miller STR-WF2 Strainer & Orifice Kit 310473 is a replacement filtration and flow-control kit designed for use in WF2U and WFE series water feeder assemblies. It includes a strainer and calibrated orifice components that regulate water flow while removing debris from the system. In HVAC systems, it is typically applied in boiler feed and hydronic heating setups where consistent water supply and controlled flow are necessary for stable operation. The kit is commonly used in maintenance or repair applications to restore proper feeding performance within heating circuits and protect internal components from blockage.
