Distribution Valves Selection, Installation, Field Testing, and Maintenance

Distribution Valves Selection, Installation, Field Testing, and Maintenance

Distribution Valves Selection, Installation, Field Testing, and Maintenance is a guide to the selection, installation, field testing, and maintenance of water distribution valves. Although the manual focuses on distribution valves, other valves, primarily used in plant operations, are also discussed. The manual provides a history of valves and a brief overview of the theory and flow characteristics of valves. It is a discussion of recommended practice, not an AWWA standard calling for compliance with certain specifications. It provides guidance on generally available valve alternatives. Questions about specific situations or applicability of specific valves should be directed to the manufacturer or supplier.

Information contained in this manual is useful for operators, technicians, and engineers for all size utilities, but it is particularly useful for small- and mediumsized organizations. The manual deals only with the more commonly used valves, including the following:

  1. globe Valve
  2. butterfly Valve
  3. plug Valve
  4. ball Valve
  5. cone Valve
  6. gate Valve
  7. check Valve

A distribution system is a piping system that delivers water at service pressure from the pressure source to the end user connection. Generally, the system originates at a treatment plant or pumping station and ends at a residential, industrial, or commercial service connection

The system may also terminate at a fire hydrant or connect to a subordinate system. Valves are a significant component of any water
distribution system and  most commonly used in the system for isolating a section of a flow line, controlling the flow, releasing air, and preventing back flow.
