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.

Proportionale Überströmventile
Die proportionalen Überströmventile der Serie R sorgen in einer Vielzahl von Gas- und Flüssigkeitsanwendungen für einen einfachen und zuverlässigen Überdruckschutz mit Einstelldrücken von 0,7 bis 413 bar (10 bis 6.000 psig). Sie öffnen allmählich, wenn der Druck über den Einstelldruck ansteigt, und schließen, wenn der Systemdruck unter den Einstelldruck fällt. Die proportionalen Überströmventile der Serie PRV sind in fünf Federdruckbereichen lieferbar und werden werkseitig auf den gewünschten Ansprechdruck eingestellt, geprüft, verplombt und gekennzeichnet.
Ent- und Belüftungsventile
Die Entlüftungsventile von Swagelok eignen sich hervorragend, um vor dem Ausbau eines Instruments Druck aus der Signalleitung abzulassen oder die Kalibrierung von Steuergeräten zu erleichtern. Verfügbare Endanschlüsse umfassen NPT- und SAE-Außengewinde. Die manuell betätigten Be- und Entlüftungs- bzw. Ablassventile sind mit NPT- oder SAE-Endanschlüssen oder Rohrleitungsadaptern von Swagelok® erhältlich.
