Description
Siemens 331-2963 Damper Pneumatic Actuator is a precisely control HVAC dampers. As a pneumatic damper actuator, it changes damper settings using air pressure, is effective in managing airflow heating, ventilation and air conditioning systems. The 4 inch stroke version of this variant (8 13 psi spring range) is intended for use in commercial and industrial HVAC applications requiring predictable performance throughout a cycle. The unit is designed for front mounting and operate in temperatures from -20°F to 150°F, providing reliability in many applications. This allows for the actuator to have greater control of its precision, resulting in better energy efficiency through optimized airflow, lower operational costs, and overall system performance. It’s a valuable component to keep.
