Siemens SSD81U NSR 3-Position Floating Actuator 24V

The Siemens SSD81U NSR 3-Position Floating Actuator is a highly effective and flexible part used for accurate control in HVAC systems. This actuator works at 24V and has a 3-position floating control type which enables it to control the position of a valve in a step-wise manner. The non-spring return (NSR) design enables the actuator to hold the last position in case of power failure and therefore, it offers reliable performance with less dependence on power. The torque rating of the SSD81U is 5 Nm and it can work with different environmental temperatures ranging from 32F to 122F.
