Stroke Testing or Partial Stroke Testing* is a preventive maintenance procedure performed to ensure that a valve will perform as designed under normal and emergency operating conditions as required by D.O.T. regulations for annual inspections. APVS will fully inspect your valve for damage, corrosion, premature wear, leaks, etc., then perform the necessary tasks to leave your valve fully functional.
* = Partial Stroke Testing is performed when the pipeline cannot be completely "shutoff" so that production may continue,
