Válvulas de Alivio Swagelok®
Las válvulas de alivio proporcional Swagelok® protegen contra excesos de presión en aplicaciones industriales generales con una gran variedad de presiones de ajuste disponibles. Las válvulas de purga y los tapones de purga permiten purgar, ventear o drenar eficazmente la presión de la línea de señal a la atmósfera.
Ver Válvulas de AlivioLas válvulas de alivio proporcional Swagelok® serie R abren gradualmente a medida que aumenta la presión, ofreciendo una protección contra excesos de presión sencilla y fiable, protegiendo a los trabajadores y ayudando a mantener unas condiciones de proceso adecuadas. Las presiones de disparo pueden configurarse en fábrica o ajustarse fácilmente en campo para adaptarse a las cambiantes condiciones operativas. Las válvulas de alivio de media presión Swagelok® serie RV pueden utilizarse en aplicaciones con presiones de operación hasta 1378 bar (20 000 psig).
Las válvulas de alivio de seguridad proporcional Swagelok® serie PRV, son válvulas certificadas según la Categoría IV de PED 2014/68/UE, y tienen el marcado CE de acuerdo con la Directiva de Equipos a Presión como válvula de seguridad según ISO-4126-1. Se ajustan, prueban, sellan y etiquetan en fábrica con la presión de disparo.
Las válvulas de purga Swagelok® serie BV pueden utilizarse en dispositivos de instrumentación como manifolds multiválvula o válvulas para manómetros, para permitir la extracción segura de los instrumentos y ayudar en la calibración de los dispositivos de control. Están disponibles con certificado de bajas emisiones (Low-E) según API 624 para reducir las emisiones incontroladas.
Los tapones de purga Swagelok® serie P son válvulas manuales de purga, venteo o drenaje. Los tapones moleteados están montados permanentemente en los cuerpos de las válvulas para mayor seguridad, y tanto las válvulas de venteo como las de purga son compactas para facilitar la instalación.

Proportional Relief Valves
R series proportional relief valves provide simple, reliable, overpressure protection for a variety of liquid or gas general-industry applications with set pressures from 10 to 6000 psig (0.7 to 413 bar). They open gradually as the pressure increases and will close when the system pressure falls below the set pressure. PRV series proportional safety relief valves are certified safety valves with five set spring pressure ranges are available with the selected set pressure factory-set, tested, locked, and tagged to ensure the desired setting.
Bleed and Purge Valves
Swagelok bleed valves can be used to vent signal line pressure to atmosphere before removal of an instrument or to assist in calibration of control devices. Male NPT and SAE end connections are available. Purge valves are manual bleed, vent, or drain valves with NPT, SAE, Swagelok® tube fitting, or tube adapter end connections.
