non spring return valve actuators

Non-spring return (NSR) valve actuators are devices that control the valve's position through continuous external power. Also called non-fail-safe valve actuators, these models open or close the valve during interruptions without dependence on a spring to return it to its default position.

How NSR Valve Actuators Work

When precise control is needed, non-fail-safe valve actuators make a difference. In some applications, their design makes them more efficient than fail-safe actuators because they stay in their last position when power or air is lost.  Electric non-spring return valve actuators use electric motors, while pneumatic models rely on an external air supply to control the valve. 

Applications in HVAC and Industrial Systems

Non-spring return valve actuators are key components in commercial, industrial and advanced residential settings. These devices hold their position during power failures, making them ideal for various applications, including: 

  • Water flow regulation: In water valves, this type of actuator can help control the flow of water in heating and cooling systems. 
  • Airflow control: The actuator provides modulating control for air handling units (AHUs) and variable air volume (VAV) systems for optimal airflow and temperature. 
  • Ventilation management: The device controls the ventilation flaps and louvers to improve the flow of outdoor, return and exhaust air.
  • Heating and cooling system operations: Non-spring models are purpose-built to modulate valves in heating and cooling systems.
  • Industrial process control: These springless valve actuators are suitable for automated, in-line process control, helping manage process flow and ensuring stability during a power interruption.
