Siemens Building Technology SKD62U Actuator
The Siemens Building Technology SKD62U Actuator is a high-performance electro-hydraulic valve actuator designed for modulating control in demanding HVACR applications. Operating on a 24Vac supply, this unit provides precise positioning for Flowrite 599 Series valves and compatible globe valves with a 3/4-inch (20 mm) stroke. The SKD62U supports both 0-10Vdc and 4-20mA control signals, selectable via internal DIP switches, making it a versatile choice for direct-coupled modulating valve control. As a veteran-grade spring return actuator, it delivers a fail-safe function that ensures the valve returns to its normal position during power loss, generating up to 250 lb (1100 N) of thrust. Built with a rugged die-cast aluminum housing, it features automatic stroke calibration and a manual override for efficient field commissioning. This Siemens electronic actuator is engineered for longevity in chilled water, hot water, and steam systems where reliable hydraulic valve automation is non-negotiable for system uptime.
Key Benefits
- Dual Signal Compatibility: Seamlessly integrates into existing loops using 0-10Vdc or 4-20mA analog control signals.
- Fail-Safe Reliability: Integrated spring return function provides immediate mechanical safety during power interruptions.
- Simplified Commissioning: Features automatic stroke calibration to eliminate manual tuning and ensure 100% precision in valve travel.
- Industrial Durability: The die-cast aluminum yoke and housing withstand high-ambient mechanical stress better than plastic alternatives.
- Manual Override: Allows for manual positioning during installation or emergency bypass scenarios without specialized tools.
Common Questions
How do you calibrate the stroke on the SKD62U?
Calibration is initiated by short-circuiting the contacts inside the calibration slot on the PCB. The actuator will then automatically run through its full travel range to store the 0% and 100% stroke positions in the EPROM.
Can this actuator be used in steam applications?
Yes, the SKD62U is suitable for liquid and low-pressure steam service; however, if the medium temperature exceeds 300°F (150°C), specialized accessories or stem heaters may be required to protect the internal components.
What does the green LED status indicate?
A flashing green LED signifies that the actuator is in calibration mode or moving to a position, while a steady green light indicates normal operation under power.
