As a piloted piston valve

allowing for remote sensing when the radiator is concealed behind cabinetry or architectural covers that would otherwise restrict airflow to a standard sensing head

preventing catastrophic equipment damage

Standard NPT Ports: 1/2" female NPT threads allow for seamless integration into existing HVACR piping systems

maintaining structural integrity even under high-pressure surges throughout the system

Trane MOT1503 Motor 322838-754 As a piloted piston valveThe Trane MOT1503 is a high reliability 1 8 HP HVAC fan motor engineered for consistent performance in residential and light commercial air handlers and furnaces. Operating at 115V and a dedicated 1070 RPM, this motor provides the precise airflow required for maintaining system static pressure and heat exchange efficiency. As a totally enclosed motor, the internal windings and stator are protected against dust, moisture, and particulate buildup,
