This Siemens Acvatix SKB62 Hydraulic Actuator is untested, as we are unable to do so in our workshop environment. Cosmetically this unit has some minor marks and scratches.

Please Note - Due to multiple QTYs being stocked under this listing the locations of damage may differ.

The Siemens Acvatix SKB62 is a heavy-duty, electrohydraulic valve actuator engineered to deliver precise modulation for large 2-port and 3-port control valves in complex HVAC and district heating networks. Operating on a 24V AC power supply, it generates a robust 2800 N positioning force over a 20 mm stroke to maintain strict flow regulation even under high differential pressures. Its defining safety feature is a mechanical spring-return mechanism that automatically forces the valve into a fail-safe closed position in under 10 seconds during a power loss. Designed for long-term operational efficiency, the unit includes an automatic stroke calibration routine upon start-up, electronic overload protection, a manual override knob, and an IP54-rated die-cast aluminium housing that reliably withstands medium fluid temperatures ranging from -25 °C up to 220 °C.
