reducing thermal drift and energy waste

Resilient Construction: Designed with high-grade internal windings and bearings for extended lifecycle in high-cycling environments

ensuring optimal system efficiency in both horizontal and vertical orientations

you eliminate intermittent operation and safeguard the system's most expensive component from power interruptions

it is professional practice to replace the gasket every time the ignitor is pulled for inspection to ensure a proper seal

Siemens Building Technology SAS81.33U Actuator 323055-751 reducing thermal drift and energyThe Siemens SAS81. 33U Actuator is a 24V electronic motor driven valve actuator engineered specifically for the Powermite 599 MT Series valves. This 3 position floating control actuator features a critical mechanical spring return (fail safe) function, ensuring that the valve returns to its normal position during a power loss event. With a 5. 5 mm (7 32 inch) stroke and a rapid 30 second run time, the Siemens SAS81. 33U provides precise modulation for
