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.

 

Frequently Asked Questions

• What is the Siemens Combustion SKP25.011U1?
  The Siemens Combustion SKP25.011U1 is a pressure regulating electro-hydraulic actuator used with compatible Siemens VG series gas valve bodies. 

• What valve bodies is the SKP25.011U1 compatible with?
  The SKP25.011U1 is designed for use with compatible Siemens VG series gas valve bodies. It can be installed on valve bodies ranging from 1/2 inch through 6 inches, depending on the approved valve configuration.

• What does the SKP25.011U1 do?
  The actuator helps regulate gas pressure and provides controlled valve operation for burner systems. It opens slowly during operation and closes immediately when power is interrupted.

• How fast does the SKP25.011U1 close?
  The actuator has a listed closing time of less than 0.8 seconds when power is interrupted. This quick-close function supports safe burner shutdown operation when installed with a compatible valve body.

• Does the SKP25.011U1 have service indicators?
  Yes. The Siemens SKP25.011U1 includes a visible valve stroke indicator and a power-on indication light. These features help technicians verify actuator position, power status, wiring, and burner startup operation during service.

• Can the actuator be rotated during installation?
  Yes. The SKP25.011U1 supports 360-degree actuator rotation, which provides flexibility for wiring access and installation positioning.

• How does the SKP25.011U1 mount to the valve body?
  The actuator mounts to the square valve flange of a compatible Siemens VG series valve body using four pre-mounted screws.

• Is the SKP25.011U1 sold as a complete gas valve?
  No. The SKP25.011U1 is the actuator portion of the assembly. It must be paired with a compatible Siemens VG series gas valve body to create the complete valve assembly.
