Where can pressure relief valves be installed?

Pressure relief valves are critical safety devices that help prevent excessive pressure buildup in refrigerant systems. Installing them in parallel allows each valve to serve as a backup for the others, ensuring that if one fails or is inoperable, the remaining valves can still function to relieve pressure.

In general, pressure relief valves should be located where they can effectively protect the entire system. Positioning them in parallel also allows for easier maintenance and testing of the individual valves without taking the entire system offline. This configuration contributes to enhanced safety and reliability in HVAC systems.

In contrast to other configurations, such as series installation or placement exclusively on the compressor, parallel installation provides the most effective and versatile solution for managing pressure across multiple components of the refrigeration system.
