Adjustable Pressure Setting Valves
Application:
'
esigned specifically for use on trailer tanNs containing dry bulN products. ,f a system blocNage
were to occur, the valves are designed to vent to atmosphere once the valve pressure setting
is achieved. The advantage of the adjustable air relief valve is that the factory preset pressure
can be tuned by -3 3 3S, to meet tanN application specific pressure requirements adMustments
should be performed by either the tank builder or tank maintenance facility).
Not intended for blower service (for blower service applications see the 2182 series air
relief valves shown on page 3)
Not Rated for ASME Coaded Service Requirements
Standards:

alves have a +

set pressure tolerance (valve opens at set pressure plus 1 PSI) and are
adjustable by -3/+
