Siemens Building Technology GCA163.1U Spring Return Modulated Adjustable Actuator 24 VAC/0-10VDC ST/SP

Siemens GCA163.1U Spring Return Actuator is a high end device fine control in HVAC systems. This actuator provides of torque with a nominal supply voltage of 24 VAC to provide powerful and reliable operation. It is modulated 0-10VDC analog control signal to enable for the precise adjustment of damper or valve locations. This spring return mechanism minimizes potential dangers from a power outage by providing guaranteed operation of the actuator to it’s default position. The is specifically designed for applications where accurate modulation and fail safe operation are necessary in ventilation, heating and air conditioning (HVAC) for improving energy efficiency air distribution and system performance.
