The SKC82.61U from Siemens is an electro-hydraulic valve actuator engineered for effectiveness in regulating flow control in various environments. This actuator functions by transforming an electrical control signal into a precise mechanical motion, thereby optimizing system control. It has a full stroke run time of 120 seconds, providing ample time for its operational movement in tasks that demand precision. Additionally, it features a quick spring return time of just 18 seconds, allowing for fast response during operation.

Rated for a voltage of 24 Vac with a tolerance of ±20%, this actuator is versatile enough to accommodate both 50 Hz and 60 Hz input frequencies. The actuator's stroke measures 1-1/2 inches (40 mm) in total length, which is suitable for various flow control mechanisms. The output force generated by the SKC82.61U is about 1000 pounds-force (lbf), making it effective for controlling demanding valve applications. Its power consumption hits up to 20 VA, establishing a balance between performance and energy efficiency.

Constructed from durable die-cast aluminum, the housing provides reliability in harsh industrial settings. The actuator adheres to the NEMA 1 rating for broader application use, while a vertical mounting option allows a transition to NEMA 3R with an optional weathershield (part number 599-10065) for additional environmental protection. Mounting is straightforward as the actuator affixes directly to compatible valves, simplifying installation in various setups.
