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
  • Access to HAWLE.MAP
