> Used in low-volume air tanks to retard excessive pressure buildup
> If pressure exceeds the relief pressure setting, the valve opens and air from the
tank is vented to atmosphere. Valve closes when pressure is reduced to the relief
pressure setting.
> Compact design, corrosion resi ant con ruction
> Con ructed of brass and ainless eel for compressed air and water service
> Available with adju able or non-adju able, factory preset, relief pressure setting
