Series EBVA Actuators have many clear and important advantages over competitor's products:
> Manual override is direct to valve -- not through a gear train -- to eliminate potentially hazardous conditions. Do not consider a valve actuator without manual override unless you have a convenient and regularly tested shutoff capability as backup.
> Many "discount" actuators are not thermally protected. They could potentially run and run until overheating leads to failure or even fire.
> Series EBVA position indicator is mechanically attached to the valve shaft and the running lights are wired to the motor. Indicator lights on most low cost actuators are electrically wired to your supplied signal. If the valve is jammed, if the motor burns out, if the gear box strips -- the light will not indicate the position of the valve -- it simply indicates your electrical signal.
Any one of these shortcomings could result in disaster under the right circumstances. We urge you to research actuator specifications carefully, and make an informed, safe decision. |

Completing the Actuator Model Number
The base actuator number above is only the first part of the specification process. The base actuator for all size valves is offered as either a standard actuator or with a combination of options, and must be specified with a suffix number. In other words, an "EBVA1" must be completed with a second number, for example, EBVA1-1. A table of these suffix numbers is below.
