Training Modules
Water Valves / Ready and Able
Director Approved training curriculum
Trainer: Sheldon Thomas, qualified training provider meeting requirements of Guidelines 4.2 and 4.3 of
O. Reg. 128/04
Course duration: full day
Learning objectives:
Trainees will learn that the water industry regards valve inspection and readiness to be a core utility activity. They will also learn the consequences of poor valve maintenance.
The training material presented here will prepare novice, and experienced, water system operators to operate a variety of valve models wisely, and will enable them to acquire a level of confidence when faced with having to manipulate water systems, whether old or new.
Course material will introduce the concept of water column energy, and will describe in detail how the act of operating a water valve can cause immediate and sometimes severe reactions within the water column moving through the pipes.
Trainees will be taught the proper by-size sequence of valve closure when isolating about a water main break, all to avoid destructive water hammer.
A very explicit explanation of the valve sealing mechanisms of several valve systems will enable the novice valve handler to envision and better understand the internal workings of the most commonly encountered water valves.
Trainees will learn how to identify weaknesses and strengths of valves by monitoring the valve performance during maintenance cycling exercises.
Students will be shown a 32-step procedure for re-building typical packing-style older gate valves, still very common in water systems.
Several brief valve-related videos are included to re-enforce the training material.
