Title: Hands-On Valve Operation and Maintenance
Description: This course will instruct you in the proper procedures for inspecting, testing, and maintaining mainline distribution valves and water mains. It will also examine the fundamentals of valve and main maintenance and detail effective maintenance management procedures with the focus on optimal operation of the distribution system. The course will also feature a hands-on instructional component where participants tear down each type of valve.
Who Should Attend: This course is designed for all distribution system operation and management personnel, especially those responsible for the installation, inspection, maintenance and repair of mainline valves and water mains. It will enable experienced utility personnel to stay informed on current accepted practice as well as provide an orientation and overview for new water operators. If you have taken the NEWWA “Hands-on” Hydrant Maintenance Course, you will find “Hands-on” Valve Operation and Maintenance the next logical step in your distribution system operation education.
Pre-requisites: None
CEUs: 0.6
Learning Objectives/Outcomes: In this interactive workshop, participants will have an opportunity to: Examine valve fundamentals - different types of valves and their methods of operation and component parts of each valve type; Examine gate valves, butterfly valves, and other valve types; Review the process of the inspection of new gate valves prior to installation; Discuss the methods for testing gate valves to verify proper performance before installation; and Examine methods of gate valve installation. Upon completion of this course and its hands on stations you will be able to: Explain the need for different types of valves in water works: gate, butterfly, plug, air relief, globe, pressure reducing; Explain methods of operation of each type of valve (including non-rising stem, operating stem, yoke); Explain the differences in the use and general function of gate versus butterfly valves; Describe the difference in maintenance procedures used to service valves of various diameters and types of valves; (gate, butterfly, plug, air relief, globe, pressure reducing); Explain how valve specifications are written and how they are used to inspect new valves upon delivery; Describe the methods used to test for proper operation of the gate valve; and Describe the most widely accepted methods of installation of various type and sizes of gate valves. Hands-On Stations - Valve Identification: Identify the type of valve and the end connections of the valve; Determine the number of turns by actual operation of the valve; Identify whether the valve is useful for throttling purposes; and Locate all seven of the major components of the valve. Valve Packing and Leakage: Identify the type of valve its function; Locate the most likely methods of leakage from within the valve; Determine the actual number of turns to open the valve by operating it; and Remove and replace packing material in the stuffing box of the valve. New Valve Inspection: Determine if the valve meets the established criteria by examination and operation in comparison to specifications provided; and Explain the type of valve best used for throttling purposes. Valve Identification Part II: Identify the specific type of valve provided at the station; Apply the formula to estimate the number of turns to open a gate valve and compare to actual numbers to open the valve; Identify the end connections of the valve provided; and Label and name the five most common parts of the valve provided.
Learning Outcome/Assessment Method: In addition to the course’s breakout group-based interactive learning stations and reports to the overall group, a multiple choice written self-assessment of learning outcomes will be administered following completion of the morning and afternoon sessions of the course. The written assessment will be comprised of straight forward multiple choice questions covering the core content of each instructional segment (presentation) and general course information for a total of ten questions. Each multiple choice question will examine your knowledge and understanding with regard to key concepts and information presented in a given segment and the overall course. There will be no trick questions. Following the completion of each assessment, a group review of the assessment will be conducted by the course facilitators and the NEWWA Education Staff proctor. Participants will “self correct” their assessments during this review and indicate their score on the top of their answer sheets. Participants must achieve a score of 7 out of 10 correct for a “passing grade”. Answer sheets will be submitted to/reviewed by NEWWA Education Staff proctor during the course sign-out process. Any participant who does not achieve the required passing score will meet with the NEWWA Education Staff proctor for an oral review/debrief following completion of the course. This will provide learners with an opportunity to re-examine assessment questions and answers, clarify information, and develop insight into their responses. It will also provide an opportunity to access additional learning support if needed.
