Johnson Controls M9220-HGA-3 Actuator 318973-401 The 1830-003 is primarily designed

The 1830-003 is primarily designed for standing pilot systems using thermocouple or thermopile sensing

Key Benefits: Optimized Airflow Efficiency: The 24-degree pitch is calibrated to maximize heat dissipation across the condenser coils

This is specifically a low-pressure cut-out switch

it provides the exact restriction needed for low-flow chilled water or hot water applications

Johnson Controls M9220-HGA-3 Actuator 318973-401 The 1830-003 is primarily designedThe Johnson Controls M9220 HGA 3 is a high torque, spring return direct coupled actuator engineered for precise control of dampers and valves in demanding HVACR environments. Delivering 177 lb in torque, this proportional actuator supports 24Vac Vdc power inputs and accepts 0 10Vdc, 2 10Vdc, or 0(4) 20mA control signals via an external 500 Ohm resistor. Designed for versatile field integration, it features adjustable zero and span settings, allowing
