Description

All Siemens SKP15 Series Electro-hydraulic actuators can be used in combination with any VG Series gas valve.  They provide safety shut‐off control for industrial and commercial burner applications.

Safety Shut-off function:

The Siemens SKP15 electro‐hydraulic actuator consists of a cylinder filled with oil.  In addition, it also consists of a piston containing an electric oscillating pump and a relief system.  When power is supplied to the actuator, the relief system closes.  The pump then moves oil from the reservoir into the pressure chamber.  Therefore this action causes the piston to move downward in the cylinder, opening the gas valve.  When power to the actuator is interrupted, the relief system opens and the gas valve closes in less than 0.8 seconds.

Position Indicator:

A position indicator is visible through the transparent window of the terminal box cover.  It shows the entire possible stroke range of the actuator.  A light is visible through the lower left transparent window of the terminal box cover.  It indicates when the actuator receives power.  An optional, non‐ adjustable Single Pole, Double Throw (SPDT) proof of closure over travel switch signals the closed position after the gas valve has closed.  An optional SPDT auxiliary switch is adjustable between 40% and 100% of the stroke.  The adjustment screw and scale are located on the right side in the terminal box.  In addition, they are visible through the transparent window of the terminal box cover.

Sealing gasket:

The AGA66 sealing gasket can be installed between the actuator and the gas valve.  In other words, this provides NEMA 3, 3R, and 4 protection rating for VGG10.xxxU / VGDxx.xxxU / VRD40.xxxU valves.
