The Siemens Combustion SKP25.011U1 is a pressure regulating electro-hydraulic actuator designed for use with Siemens VG series gas valve bodies in commercial and industrial burner applications.  When assembled with a compatible VG gas valve body, the actuator provides gas pressure regulation and safety shutoff in one compact gas train component.  This unit is UL-Listed, FM, and CSA-certified.

This actuator operates on 110 to 120 VAC power at 50/60 Hz and uses a low 13.5 VA power draw. The SKP25.011U1 opens slowly during operation and closes immediately when power is interrupted, with a listed closing time of less than 0.8 seconds. A visible valve stroke indicator and power-on indication light support easier field verification during service, wiring, and burner startup.

The modular actuator design allows installation on compatible VG series valve bodies from 1/2 inch through 6 inches. The actuator mounts to the square valve flange using four pre-mounted screws and supports 360-degree actuator rotation for wiring and installation flexibility.
