and low-voltage controllers that are susceptible to the high-frequency interference common in switching power supplies

Integrated manual override lever allows for easy bypass and system testing without electrical power

though standard visual inspections for debris in the line are recommended to protect the valve seats

meeting the latest UL standards for smoke control systems

reducing energy waste and preventing bypass flow when the valve is commanded closed
