Siemens SKP25.403E2 actuator
Precision electrohydraulic actuator-regulator Siemens SKP25.403E2 (art. 884.712.208). Ideal solution for automation of gas burners and industrial furnaces. Siemens SKP25.403E2 is not just an actuator, but a high-tech electrohydraulic final control element with an integrated gas pressure regulator. This model is the "heart" of the gas safety and control system in modern boiler equipment. It replaces the outdated SKP20 series, offering increased reliability, energy efficiency, and compliance with strict European safety standards (EN161). If you need to ensure stable combustion, precise gas-air ratio, and instantaneous fuel shut-off in an emergency, SKP25.403E2 is your uncompromising choice. Why buy SKP25.403E2? Key advantages: Two functions in one housing: Unlike simple actuators, this model combines an actuator for valve control and a precise constant pressure regulator (with adjustment range up to 150 mbar). You don't need to buy separate pressure reducing equipment — this saves space in the cabinet and project budget. Safety first: The actuator complies with EN 161 for shut-off valves. In case of power failure or emergency, the valve closes in a fraction of a second (less than 1 second). This eliminates gas leakage into the combustion chamber and guarantees explosion safety of your facility. Energy efficiency: The device consumes only 13.5 VA. This "smart" power consumption saves electricity during long burner cycles, reducing operating costs. Smooth ignition: The "slow opening" function (full stroke in 6-10 seconds) prevents "pops" during ignition, ensuring a smooth gas pressure increase and gentle mode for the burner.
