Description

The Siemens compact VOG opens slowly when power is on. If power interrupts, it closes in less than a second. In summary, it has a visible position indication on the front of the actuator displays position, and a light indicates when the actuator has power.

Siemens VOG15 is an electro-hydraulic actuator three-way oil valve design. It provides safety shut-off control for industrial and commercial burner applications. The normally closed port on the valve is rated for safety shut-off function. The normally open port location is on the bottom of the valve is typically used for recirculation of heavier oils.  A 3/4-inch NPT pipe plug (comes with VOG) is in the bottom port for two-way applications. The compact VOG15 actuator opens slowly when power is on and if power interrupts, it closes in less than a second. A visible position indicator on the front of the actuator displays position, and a light indicates when the actuator is on.

Operation

The electro-hydraulic actuator consists of a cylinder filled with oil, a piston containing an electric oscillating pump, and a relief system. Supply power to the actuator, then the relief system closes, and the pump moves the piston downward in the cylinder, opening the oil valve. If power interrupts to the actuator, the relief system opens and the oil valve closes in less than one second. A position indicator, visible through the transparent portion of the terminal cover, shows the entire stroke range of the actuator. The oil valve only uses about 1/4-inch of the actuator’s stroke. A light, which is visible through the lower left transparent portion of the terminal cover, indicates when the actuator receives power.

A non-adjustable SPDT POC over travel switch signals the valve closed position after the oil valve has closed. If optional equipment supplies an SPDT auxiliary switch, it changes state when the oil valve is more than 80% open.
