The Siemens SKP15.000E2 is part of the SKP electro-hydraulic actuator family designed for use with Siemens VG… gas valve bodies to form safety shutoff valves on gas-fired combustion systems. It is a 1-stage actuator without integrated regulator, providing simple open/closed operation with slow opening and rapid spring‑return closing to ensure safe fuel shutoff in case of power loss. The actuator is suitable for gases of gas families I to III and is commonly used on burners, boilers, and industrial furnaces.
Operated from a 220–240 V AC, 50/60 Hz power supply, the SKP15.000E2 drives the valve open electro‑hydraulically against a closing spring and then holds it open as long as power is applied. When power is removed, the internal hydraulic system and spring force close the valve quickly; the return flow is sized so the fully closed position is reached in about 0.6 seconds, as described in the SKP manual. The actuator features very low power consumption, optional end‑switch versions in the SKP15 range (this “000E2” version is specified “without stroke indication” in Siemens’ catalog), plug‑in electrical connection, electrical indication of operation, and conformity with EN 161 for automatic shutoff valves.
The SKP15 actuators are used exclusively as safety shutoff valves when combined with VG… valve bodies, whereas SKP25/55/75 variants provide additional governor or ratio control functions. This makes SKP15.000E2 a straightforward choice for applications that only need reliable on/off gas shutoff, without integrated pressure regulation. Multiple boiler and burner spare‑parts suppliers list SKP15.000E2 (often cross‑referenced with SKP10.110B27) as a direct replacement actuator for commercial and industrial boilers, highlighting its role as a service spare to restore safety shutoff function.
