ABRA-A5 Electric Thermal Actuator, ON/OFF
For Use with RA2000 Valves
Application |
|
base adapters are offered for the potential use of |
|
||
|
|
the ABRA-A5 to other non-Danfoss valve bodies. |
|
|
Features include: |
|
|
• 4.0mm stem travel |
|
|
• Normally closed (NC) actuator without power |
|
|
• Low power consumption 1 W |
|
|
• Actuator installed in any orientation |
|
|
• Position indicator |
|
|
• Silent operation |
|
|
|
The ABRA-A5 ON/OFF zone valve actuator has been specifically designed for use with Danfoss RA2000, RA-C, and RA15/6 series of valves used for heating and cooling applications. Additional
Function |
The actuator mechanism of the ABRA-A5 |
|
actuator uses a heated wax element and positive |
||
|
||
|
temperature coefficient (PTC) resistor to allow the |
|
|
actuator to open. On the call for heat the wax |
|
|
element is heated by the resistor and the valve |
|
|
begins to open. |
|
|
First open function |
|
|
In its delivery condition, the ABRA-A5 is partially |
|
|
open, 50%, to assist in the mounting of the |
|
|
actuator and filling of the system. Until the |
|
|
actuator is energized, the actuator is partially |
|
|
open. When power is wired to the actuator the |
|
|
first open function is unlocked and by applying |
|
|
the operating voltage for more than 6 minutes |
|
|
the ABRA-A5 will then be completely operable. |
|
|
NC “normally closed” |
|
|
Without power or signal to the actuator its |
|
|
position is fully closed. Only when power is |
|
|
supplied will the actuator open. When power is |
|
|
removed the actuator closes in the same steady |
|
|
rate by the closing force of the compression |
|
|
spring. The closing force and travel of the |
|
|
actuator matches the valve and keeps the valve |
|
|
closed when de-energized. |
|
|
End switch |
|
|
The integrated micro switch (end switch) closes at |
|
|
approximately 2mm or 50% of actuator travel |
|
|
from closed position. From full open when the |
|
|
operating voltage is removed, the micro switch |
|
|
closes at approximately 2mm or at 50% closing. |
|
|
Position Indication |
|
|
The position indicator of the ABRA-A5 is located |
|
|
on the top of the actuator. This visual position |
|
|
feedback allows identifying the operating |
|
|
condition (valve open or closed) at a glance. |
