Dixon Bayco Air 2″ Pressure Relief Valves

Originally designed for bulk transport trucks, the 2182 air relief valves accommodate the high temperatures and dynamic air from blowers, with a temperature compensated pressure relief setting.  If a system blockage were to occur, the valves are designed to vent to atmosphere once the valve pressure setting is achieved.

Dixon Pressure Valve Features

• High relieving capacity varies between 800 SCFM and 1700 SCFM depending upon the chosen set pressure.
• Installed cup seal deters tampering
• Anodized aluminum body reduces thread galling
• Constructed with aluminum anodized hard coat and white food grade silicone poppet and diaphragm

The 2182 valve will relieve at the ordered set pressure at a temperature of 400°F / 204°C. At room temperature 73°F / 22°C the 2182 valve will relieve approximately 4 PSI higher than the ordered set pressure.  The product label shows the set relief pressure at the blow operating temperature, plus the relief pressure at 73°F / 22°C (for testing purposes). Depending on the blower type, amount of vibration and operating temperature a difference of observable set pressure may occur.
Example: 2182-18 is set to relieve at 18 PSI while at operating temperature. This same valve will test at 22 PSI while at room temperature on a test bench. Both set points are listed on the label.
