Adjustable Pressure Setting Valves

Application:

Designed specically for use on trailer tanks containing dry bulk products. If a system blockage

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 PSI to meet tank/application specic pressure requirements (adjustments 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)

Standards:

Valves have a +1/-0 set pressure tolerance (valve opens at set pressure plus 1 PSI) and are adjust-

able by -3/+3 PSI.

• A2180ADJ has a 2" female NPT and A3180ADJ has a 3" female NPT connection

Materials:

Bayloy vent cowl with aluminum upper, bronze poppet with white food grade silicone diaphragm in

the 2180/A2180, red silicone diaphragm in the 3180/A3180

Features & Benets:

• Available with a variety of pressure settings, see chart below for model specic available pressure

settings. Customer should request set pressure at time of order.

• The factory preset pressure can be tuned by -3/+3 PSI to meet tank/application specic pressure

requirements (adjustments should be performed by either the tank builder or tank maintenance

facility).

• Relieving capacity (SCFM) varies dependent upon model and pressure setting. See chart below,

or for specic relief rates please refer to our website or contact Dixon.

• Installed cup seal deters tampering

• Bayloy body eliminates thread galling

A2180-xxADJ

¹ request the required pressure setting when ordering (xx refers to choice of pressure setting)

² relieving capacity (SCFM) varies with set pressure, for specic rates please refer to our website or contact Dixon
