VOG15.01xU1 Oil Safety Shut-off

Valves with Proof of Closure (POC)

Oil Safety Shutoff Valve

Description

The VOG15 is an electro-hydraulically actuated three-way oil valve designed to provide

safety shut-off control for industrial and commercial burner applications. The normally

closed port on the valve is rated for safety shut-off function and the normally open port

located on the bottom of the valve is typically used for recirculation of heavier oils. A

3/4-inch NPT pipe plug (provided) must be used in the bottom port for two-way

applications.

The compact VOG15 actuator opens slowly when power is applied and closes in less

than a second when power is interrupted. A visible position indicator on the front of the

actuator displays position, and a light indicates when the actuator is powered.

Features

• UL listed, FM approved, CSA certified, ISO 9001 and ISO 14001 certified.

• Proof of Closure (POC) with Over Travel

• UL listed as watertight in the vertical position

• Visual position indication

• "Power on" indication light

• Quick connect wiring terminals

• Optional auxiliary switch available

• Actuator can be rotated 360

with respect to valve for easy field wiring and

installation.

• Low, 20 VA power consumption.

Application

The VOG15 is designed to be used as a two- or three-way valve on industrial and

commercial burners firing No. 2 to No. 6 fuel oil having a maximum viscosity of 5,000

SSU.

VOG Series Oil Safety Shut-off Valves with Proof of Closure Operation Installation Instructions Document Number 129-464 March 16, 2009 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 the piston downward in the cylinder, opening the oil valve.
