Direct Installation - omal automation DA2880 Installation, Use And Maintenance Manual

Prior to installation verify that valve and actuator comply with the safety standards described above. Ut-
most cleanliness is required when connecting the air supply to the actuator. All parts of the plant, reduc-
tions, joints, plates, brackets and equipment must be thoroughly cleaned. Before mounting the actuator
on the valve be sure that both elements are correctly oriented, depending on the rotation direction nee-
ded.
- Before installation, visually check that the conditions of the actuator are good, since it's been transported
and stored.
- Carefully read the OMAL S.p.A. instructions contained in the cardboard box.
- Verify performance and limits found on the actuator body to see whether if it's suitable for the application
or not.
- Remove the plastic protective covers from the ports and insert whichever filters as pointed out in para-
graph 2.
- Prior to mounting the actuator on the valve, clean both from dust and dirt.
- Verify the valve position, closed or open, and the rotation direction.
- Verify the actuator position and the rotation direction based on the valve, especially for the installation of
the SR version "normally closed" and "normally open".
- The SR versions "normally closed" are always supplied in the closed position.
The SR versions "normally open" are always supplied in the open position.
Assembly of Valve/Actuator:
A) DIRECT INSTALLATION
The direct installation of valve and actuator is the best way in order to avoid backlash between the valve
stem and the actuator shaft. For direct installation, there should be the same standard flange connection
both on the valve and on the actuator, and the dimensions of the valve stem should fit perfectly with those
of the actuator shaft. Before installation, please check that the actuator and the valve both have ISO flan-
ges of the same size, also check that the dimensions of the valve stem and its shape are suitable for direct
mounting: use a reduction if necessary.
Mount the valve stem in the housing on the actuator shaft and bolt the two ISO flanges together.
