Danfoss 003Z1321 Valve 318518-761 Robust Flame Sensing: Utilizes advancedThe 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
