this OEM part is engineered to detect abnormal high-temperature conditions—specifically flame rollout—and immediately break the electrical circuit to shut down the gas valve

safety float switches are typically sold separately as field-installed accessories

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

LBP Performance: Optimized for low back pressure environments

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

Bray Commercial DCM24-44-AP Actuator R-407A this OEM part is engineeredThe 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
