In which piping systems should shutoff valves be installed according to specified sections?

Shutoff valves are essential components in various piping systems, providing the ability to quickly isolate sections of a system for maintenance or in case of a leak. The installation of these valves is governed by various codes to ensure safety and operational efficiency.

In ground-source loop piping systems, shutoff valves are particularly important for controlling the flow of refrigerant or fluid circulating in the geothermal heat exchange process. Installing shutoff valves in these systems allows for necessary maintenance and adjustments without compromising the entire system's operation.

This makes the inclusion of shutoff valves a crucial safety feature, as it enables the isolation of specific portions of the loop for repairs, testing, or replacement without requiring the entire system to be drained or shut down.

While hydronic, hot, and cold water systems also require shutoff valves, the specific focus on ground-source loop piping systems relates to unique requirements for managing the flow of fluids that are often subject to more intense pressure and varied temperature conditions, thus reinforcing the importance of these valves in that context.
