Siemens Building Technology SKB62UA Actuator
The Siemens Building Technology SKB62UA Actuator is a heavy-duty electro-hydraulic actuator designed for the precise modulation of 24VAC HVAC valves. Delivering a robust 2800 N (640 lbs) of positioning force, this proportional control unit is engineered for Flowrite 599 Series globe valves and other compatible bodies with a 20mm (3/4-inch) stroke. Featuring advanced electronics, it supports multiple control signals, including 0-10 Vdc, 4-20 mA, and 0-1000 Ohm resistance, ensuring seamless integration into varied building automation systems. The integrated spring return fail-safe function ensures the valve returns to the 0% stroke position (fully retracted) upon power loss, protecting critical equipment in heating, cooling, and steam applications. With a die-cast aluminum housing and NEMA 1 rating (upgradable to IP54/NEMA 3R with a weather shield), the SKB62UA provides a maintenance-free solution for large-scale commercial air handling units and district energy systems.
- Universal Modulation: Compatible with DC 0-10V and 4-20mA signals for versatile HVAC valve control.
- High Positioning Force: 2800 N (640 lbs) force rating handles high differential pressures in steam and liquid service.
- Fail-Safe Reliability: Mechanical spring return (SR) provides a 10-second closing time during power outages.
- Simplified Commissioning: Automatic stroke calibration and visual travel indicators streamline field setup.
- Advanced Logic: Built-in sequence control, stroke limit control, and selectable flow characteristics (linear or equal percentage).
Common Questions
What is the primary difference between the SKB62UA and the SKC62UA?
The SKB62UA is designed for valves with a 20mm (3/4-inch) stroke, while the SKC62UA is built for larger 40mm (1-1/2-inch) stroke valve bodies.
Can this actuator be used in outdoor environments?
Yes, when installed vertically with a Siemens-approved weather shield (P/N 599-10065), the unit meets NEMA Type 3R requirements for protection against rain and sleet.
How do I calibrate the stroke after installation?
The SKB62UA features an automatic calibration slot on the circuit board; shorting these contacts initiates a self-calibration sequence that stores the 0% and 100% stroke positions in the EPROM.
