1. INTRODUCTION

The Siemens electro-hydraulic gas valve actuators are used in combination with VG series gas
valves to provide safety shut-off control for industrial and commercial burner applications. It is
featured in all double-block and double-block-and-bleed gas trains used in AERCO boilers.

The electro-hydraulic actuator consists of a cylinder filled with oil, a piston containing an electric
oscillating pump, and a relief system. When power is supplied to the actuator, the relief system
closes, and the pump moves oil from the reservoir into the pressure chamber. 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. A position indicator, visible through the transparent portion of the terminal cover,
shows the entire stroke range of the actuator. A light, which is visible through the lower left
transparent portion of the terminal cover, indicates when the actuator receives power. An
optional, non-adjustable 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, and are visible through the transparent portion of the terminal cover.
