Valves - Intro Distribution (1.25 Contact Hours)

Valves play a vital role in every drinking water distribution system. In this course, participants will learn about the major types of valves—such as gate, butterfly, globe, check, pressure reducing, and altitude valves—and their specific functions like starting/stopping flow, regulating pressure, preventing backflow, and relieving pressure. The training covers proper operation procedures, installation guidelines, and critical maintenance practices, including valve exercising programs.

Special topics include the impact of valves on system performance (e.g., minimizing water hammer), valve actuators (manual, electric, hydraulic, pneumatic), and best practices for valve placement in residential and urban distribution networks.

Key Topics Covered:

• Types of valves and their specific applications

• System isolation techniques

• Pressure control and relief mechanisms

• Preventing backflow into potable water systems

• Proper valve operation and maintenance

• Valve exercising programs and preventive care

• Emergency procedures and troubleshooting

Who Should Enroll:

• Water system operators

• Distribution system maintenance staff

• Public works employees

• Professionals preparing for California water distribution certification exams (D1–D5)

Learning Outcomes: By the end of the course, students will be able to:

• Identify and describe various valve types and their uses

• Select the appropriate valve for different distribution system needs

• Perform essential maintenance tasks like valve exercising

• Prevent common system failures such as backflow and pressure surges

• Apply California-specific standards and best practices in daily operations
