Course Content

To provide the skills and knowledge of the operation, calibration and industrial application of process control valves used for the manipulation and control of the main process variables of pressure, level, flow and temperature.

The course is ideally suited to those personnel who may require training as part of a multi-discipline engineering programme and who are required to carry out work with control valves on return to their workplace.

The course will be of five day's duration.

Optimum Number:
The optimum number of persons on this course will be six.

Training Aids:
A Roxby Presentation using course hand outs.  This is followed with practical training and assessments.

Course Language:
The course is delivered in English.  Therefore candidates must have good standards of both written and verbal English.  Courses can be delivered in other languages, however this would need to be discussed prior to acceptance on the course.  It is the responsibility of the person making the booking to make Roxby aware of this requirement
