NCO 373-03163 2-Wire N/O Non-Spring-Return (FxF) Valve Actuator The NCO 373-03163 is a 2-wire, N/O (normally open), non-spring-return (FxF) valve actuator manufactured by Siemens Building Technology. This actuator provides precise control over valves in various heating, ventilation, air conditioning, and refrigeration (HVACR) systems. Key Features: Normally Open (N/O) Operation: The valve is normally in the open position when the actuator is de-energized. Non-Spring-Return (FxF): The valve remains in the last position until a control signal changes it. 2-Wire Control: Simplified wiring for easy installation. 24V Voltage: Compatible with standard HVACR control systems. 1/2" NPT Inlet: Fits standard 1/2" NPT valve connections. Compact and Durable: Designed for long-term performance in harsh environments. Applications: The NCO 373-03163 actuator is ideal for controlling valves in: * Heating and cooling systems * Ventilation systems * Air conditioning systems * Refrigeration systems Benefits: * Precise valve control for efficient system operation * Reliable performance even in demanding conditions * Easy installation and maintenance * Enhanced energy efficiency Shop our HVAC supply store for the Best Prices and Fast Shipping
