Description
The Siemens SKD62U is a spring-return rotary actuator engineered for precise valve control in commercial building automation and HVAC hydronic systems. Accepting both 0–10 VDC and 4–20 mA control signals, this actuator delivers flexible integration with a wide range of building automation system (BAS) controllers and DDC platforms. Powered by a 24V supply, the SKD62U is designed for dependable, fail-safe operation — the spring-return mechanism automatically drives the valve to its safety position upon loss of power or control signal.
