this actuator is a direct drop-in for IEC B035-71488507 models

making it the industry standard for proving airflow in package burners and furnaces

Field technicians often utilize this compressor start relay to resolve hard-start issues in systems experiencing high head pressures or erratic voltage

PVE is preferred over POE because it does not require the same level of moisture-critical handling while providing excellent miscibility with HFCs

this valve features an automatically reseating design that ensures the system returns to normal operation independently after a relief event
