Danfoss 003Z1321 Valve 340155-7026 Key Benefits: Precise Pressure Regulation:

Key Benefits: Precise Pressure Regulation: Features a factory-calibrated 660 PSI cutout and 505 PSI cut-in for consistent system protection

30VA Efficiency: Optimized for low-voltage relays and controls without excessive footprint or energy waste

which often indicate the vent hood damper assembly is not opening or closing correctly

maintaining identical physical dimensions and pressure ratings

By maintaining tight voltage regulation and signal integrity

Danfoss 003Z1321 Valve 340155-7026 Key Benefits: Precise Pressure Regulation:The 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
