About the Event

Valves

Course Objectives

The purpose of this course is to improve technician performance both in practical terms and in underpinning knowledge.

Course Description

The course will cover the subjects described on the enclosed syllabus. The course will comprise practical and theoretical instruction. The purpose of this course is to improve technician performance both in practical terms and in underpinning knowledge. Each trainee will benefit from the latest technologies, taught both practically and by formal lecture/demonstration.

Assessment will be by practical assignments and simulations. Valve positioners will also be taught along with split-range control systems. Each trainee will carry out the practical tasks of stroke checking a pneumatic valve, mounting a positioner and calibrating a positioner.

Who should attend

This course is aimed at those maintenance technicians that require knowledge of the maintenance aspects of a variety of valve types.

Pre-Requisites

All Attendees should have a sound power generation and electrical background.

Course Outcome

At the end of this course you will be able to maintain valves.
