What is the acceptable pressure range for the air line pressure relief valve (PRV)?

The pressure range of 5-10 psi for the air line pressure relief valve (PRV) is considered acceptable because it aligns with industry standards and safety regulations for sprinkler systems. This range allows for effective operation without risking damage to the system due to over-pressurization.

Maintaining the PRV within this pressure range ensures that air is adequately vented when necessary, preventing the build-up of excessive pressure that could compromise the integrity and functionality of the sprinkler system. An excessively high pressure could lead to leaks or even system failure, while too low a pressure might not provide the necessary performance from the system.

Understanding these operational parameters is critical for anyone involved in the installation and maintenance of sprinkler systems, as it helps maintain their effectiveness and reliability in fire protection scenarios.
