Neoperl - Model PR -Check Valves with Pressure Relief

Check valves fitted with a Pressure Relief (-PR) valve allow a few drops to bypass the check valve when the back pressure exceeds 20,5 (± 4,5) bar. This immediately relieves the pressure and prevents damage to the faucet. Below 16 bar, the PR check valve operates as regular check valve in compliance with EN 13959. Applicable wherever high back pressure may occur in closed systems.
