● 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 resistant construction
● Constructed of brass and stainless steel for
compressed air and water service
● Available with adjustable or non-adjustable, factory
preset, relief pressure setting
