The Siemens SKB62UA electro-hydraulic actuator falls under the Flowrite 599 Series. It is constructed with a robust die-cast aluminum housing and is rated for an IP54 enclosure, providing effective protection against dust and liquid ingress. The actuator’s NEMA 1 rating indicates it is suitable for interior use only. With a fail-safe spring return mechanism in place, this unit guarantees operational reliability in case of power failure.
Operating at a nominal voltage of 24 VAC, the SKB62UA functions effectively within a voltage range of 19.2 to 28.2 VAC. The actuator generates a positioning force of 4000 N, essential for adjusting valves accurately. It can accommodate a valve stroke length of 3/4 inches (20 mm), optimizing performance in various applications.
Positioning signals can be adjusted between 0-10V DC, 4-20 mA, or 0-1000 Ohm, allowing for compatible integration with an array of control systems. The actuator is capable of opening within a 120-second timeframe and can close in just 10 seconds, facilitating efficient operation. Ambient temperature specifications range from -15°C to 55°C, enabling it to perform in diverse environmental conditions.
Notable features of the SKB62UA include automatic stroke calibration, stroke limit control, and a manual override option. Users can also select between direct or reverse acting modes and adjust the start and span settings for optimal operation. Overall, the SKB62UA actuator delivers a versatile solution for hydraulic control in automated systems.
