8 MAINTENANCE 

Control and function test should be carried out every three years. In case of heavy loads of the actuator (and the 
valve) the intervals should be shorter. The Oden

 

actuator gears and the bearings need no lubrication or service. 

8.1. Check 

points 

Electronic contact control 

Control and clean the surfaces in the terminal blocks at the connection board. 

Torque control 

With the OVP software, it is possible to control the condition of the valve by slowly increasing the control 
torque/force until the actuator starts moving. You will notice a change in valve bearing condition. 

Calibration control 

Perform a new Power or Position calibration to verify closed position. 

Positioning control 

Position the valve near the middle of the working range. Increase the control signal very slowly until the valve 
spindle starts to move. Read the mA-value. Decrease the control signal very slowly until the valve spindle starts to 
move in the other direction. Read the mA-value. The signal difference is a measure of the “control backlash” of the 
system (positioning accuracy). 

First check that it is no mechanical backlash in the coupling between the valve spindle and actuator. It is possible 
to measure the valve motion by using an indicator clock against a pin fitted to one of the free M10 threads in the 
clamp collar (turning valve). A common cause for backlash is that the spindle adapter is not properly fixed to the 
valve spindle. 

Note that in some applications most of the total mechanical backlash in the system is eliminated by the media in 
the pipe system which will give a torque/force load at the valve spindle always in the same direction. Hence, this 
test should be performed on a normally pressurised system. Some valves have high internal friction. In such valves 
the backlash will have a direct influence on the positioning accuracy.
