The Siemens SSB81U Powermite 599 MZ Series SSB electronic valve actuator 24 Vac is designed to work with Powermite 599 MZ Series zone control valves, which need 45 lb. (200N) nominal force, within liquid or steam heating and cooling HVAC applications.
Features
The Siemens SSB81U requires a 24 Vac supply floating control signal to provide three-position control. This actuator is designed to work with Powermite 599 MZ Series zone control valves with a 7/32-inch (5.5 mm) stroke and a threaded valve bonnet that fits the actuator. For use in heating and cooling HVAC applications with Powermite 599 MZ Series valves that need 45 lb. (200N) nominal force. They can be used in liquid and steam service applications.
