Swagelok® Proportional Safety Relief Valves
PRV series proportional safety relief valves provide over-pressure protection with PED certification.
Connect to Learn MorePRV series proportional safety relief valves are available in five set spring pressure ranges and are factory-set, tested, locked, and tagged to ensure the desired setting. They open gradually as the pressure increases above the set pressure and close when system pressure falls below the set pressure.
In addition, PRV series relief valves are:
- Certified to PED 2014/68/EU Category IV
- CE-marked in accordance with the PED as a safety valve according to ISO-4126-1
Optional end connection adapters provide flexibility for installation in a variety of system setups.
