Elektrogas S Series Actuators

Elektrogas S is a series of solenoid actuators that can be used with Elektrogas VF, VFH, and VFT butterfly valves.

The hardware needed to mate VFH to S is included with the actuator, there is no additional hardware to buy. The VFH is a high-temp model; a long stem keeps the actuator from the hot pipe. If you don’t require a high temp model, a better choice is the VF. High temperature butterfly valves are more expensive, so if you don’t need high-temp, why pay more? Other manufacturers don’t provide a choice.

If you want to connect to VFT, you’ll need Set ST. If you want to connect to VF, you’ll need set S. For very high temps, a Set D is available.

Fixing Set point

The Elektrogas S actuator uses a different method for fixing the set point, compared to the competition. If you’ve shied away from solenoid actuators due to frustration with lock nuts that won’t hold their position and set screws that easily strip, you’ll be happy to find these issues aren’t applicable for Elektrogas.

There is a set screw on the bottom of the actuator (fig. 29) that is removed, allowing access to an inner screw which is used to set the low-fire (fig. 30). Similarly, the top of the unit has a screw (fig. 33) which is used to set the high-fire. (fig. 34) Once the inner screws have been set, simply tighten the set screws back up and you’re finished fixing the set point.
