Specialty Valve Training

Presented By Cimco-GC Systems

in Collaboration with PNWS-AWWA Engineering Committee

March 19, 2024

Engineers and operators alike will learn about "specialty" valves which include hydraulic control valves, air valves, and check valves. This discussion begins with basic hydraulics and how hydraulics automatically operate control valves to manage system pressure, flow, reservoir levels, and pumps. The 3-hour hands-on session on control valves will demonstrate valve and pilot internals, sizing, design, troubleshooting, and maintenance. Some attendees will have the opportunity to start-up, operate, and shut down a valve under live pressure!

The additional 2-hours will focus on check and air valves and how they are critical to a functionuing water distribution system. This section will highlight six different check valves, selection and function. This will include education on "slamming" and preventing it. Further discussion will include the problem of air in the system, why air must be eliminated regularly, how air valves work, and selection of air valves. Live models of both air and check valves will be present for engineers and operators to see how these valves operate in water systems.

    CEU Relevancy Statement:

    Specialty vavles and maintenance are a vital aspect of a functioning water system. Proper understanding, maintenance, and design practicies will aid to ensure proper valve performance and prevent valve failure which affects system reliabitliy, community safety, resource (water) protection, and resource concservation. Hydraulic control valves especially remain a myster to many engineers and operators. This class is designed to build a fundamental familiarity with valve function and hydraulic piloting systems. When a specialty valve is needed for a new installation or replacement, engineers, and operators will have a better understanding of function, design, and selection.
