Industrial Durability: Constructed from carbon steel to resist bowing and fatigue in 24/7 commercial air handler operations

the S1-R72DB0044 is specifically calibrated for R-410A refrigerant pressures and cannot be used in R-22 applications

making it compatible with standard dual-voltage supply lines common in commercial HVAC applications

If your multimeter reads below 20 mV under load

System Protection: Helps prevent electrical faults and ensures proper communication between the control board and solenoid valves

Bray Commercial DCM24-44-AP Actuator R-407A Industrial Durability: Constructed from carbonThe Bray Commercial DCM24 44 AP Actuator is a high precision, non spring return actuator designed for the demanding requirements of modern building automation systems. Operating on a 24VAC supply, this unit delivers a consistent 44 in lb torque, making it an ideal choice for modulating control of dampers and valves in HVACR applications. The actuator accepts a 0 10VDC control signal, providing seamless integration with standard building controllers
