Gate valve – control maintenance
Process:
- The street cap is cleaned.
- The slide is fully actuated several times with a newly developed, electronic rotary actuator
and the torque-displacement curve is recorded in the process.
This allows to draw conclusions about the condition of the valve.
If, for example, the target number of gears is reached, this is a good indication of the continued
tight closure. Actuating the slides several times makes them move more smoothly again.
Even stuck or very stiff fittings can be repaired in many cases. - Tightness control
- The geo-position is recorded, the master data is created in the database.
- Control and update of the information for the line plan
- Test reports in printed and/or electronic form – GIS import possible
