Always check the current capacitor’s mfd rating during replacement to ensure the new motor operates within its designed amperage range

you should utilize an adjustable dual pressure control instead

It is designed to be swapped into your existing centrifugal blower assembly

meaning it will restore the circuit once the pressure drops below the set differential

Danfoss 003Z1321 Valve 326010-701 Always check the current capacitor’sThe Danfoss 003Z1321 is a high performance AB QM Pressure Independent Control Valve (PICV) designed for precision flow regulation in HVAC systems. Featuring a 1 2" connection and a flow range of 0. 25 to 1. 2 GPM, this valve eliminates the need for manual balancing by maintaining a constant differential pressure across the control orifice. This dynamic balancing valve ensures that flow remain stable despite pressure fluctuations elsewhere in the
