Swagelok® Relief Valves
Swagelok® proportional relief valves provide overpressure protection in general industrial applications with a variety of set pressures available. Bleed and purge valves provide effective bleeding, venting, or draining of signal line pressure to atmosphere.
View Relief ValvesSwagelok® R series proportional relief valves open gradually as pressure increases, providing simple, reliable overpressure protection, protecting workers, and helping to maintain proper process conditions. Set pressures can be configured at the factory or easily adjusted in the field to suit changing operating conditions. Swagelok® RV series medium-pressure relief valves can be used in applications with operating pressures up to 20 000 psig (1378 bar).
Swagelok® PRV series proportional safety relief valves are certified to PED 2014/68/EU Category IV and CE-marked in accordance with the Pressure Equipment Directive as a safety valve according to ISO-4126-1. They are factory-set, tested, locked, and tagged with the set pressure.
Swagelok® BV series bleed valves can be used on instrumentation devices such as multivalve manifolds or gauge valves to allow safe removal of instruments and to assist in the calibration of control devices. They are available with low emission (Low-E) certification according to API 624 to combat fugitive emissions.
Swagelok® P series purge valves are manual bleed, vent, or drain valves. Knurled caps are permanently assembled to valve bodies for safety, and both bleed and purge valves are compact for convenient installation.
