Do not mix/interchange Swagelok two-ferrule tube-fitting end connection components (or other products not governed by industrial design standards) with those of other manufacturers. Optional end connection adapters provide additional flexibility for installation in a variety of system setups. The set pressure can be set at the factory or easily adjusted in the field. When selecting products, the total system design must be considered to ensure safe, trouble-free performance. Available factory-installed or in kits for field assembly. PRV series proportional safety relief valves are certified to PED 2014/68/EU Category IV, CE-marked in accordance with the Pressure Equipment Directive as a safety valve according to ISO-4126-1, and factory-set, tested, locked, and tagged with the set pressure. Proportional relief valves provide overpressure protection with a variety of set pressures available. For applications needing to drain signal line pressure to atmosphere, bleed and purge valves will manually bleed, vent, or drain that pressure. The item you've selected was not added to your cart.
