ensuring that seating and alignment meet original factory specifications

When your mechanical schedule calls for precise modulation in high-demand hydronic or steam systems

the pilot operated mechanism handles pressure ranges from 5 to 150 PSI for air/water and up to 100 PSI for light oil systems

ensuring it handles the localized voltage spikes typical during start-up

contaminant-free air in compressed air systems

Nordyne 632566 Pressure Switch 328140-751 ensuring that seating and alignmentThe Nordyne 632566 Pressure Switch is a critical safety component designed for specific gas fired furnaces and packaged units. As the direct replacement for 632566R, this differential pressure switch monitors the pressure drop across the heat exchanger, ensuring the induced draft motor is evacuating flue gases effectively before allowing the ignition sequence to proceed. This single pole, normally open switch is calibrated to precise OEM
