Products for Blowers
Application:
Designed specifically for use on tractor mounted air blowers. The 2182 air relief valves have a
temperature compensated pressure relief setting to accommodate the high temperatures and
dynamic air produced by the blower. If a system blockage were to occur, the valves are designed
to vent to atmosphere once the valve pressure setting is achieved.
Standards:
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 blower 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.
Available with 2" male or female NPT connections.
Materials:
Aluminum anodized hard coat body, white food grade silicone poppet and diaphragm
Features & Benefits:
•
The popular pressure setting for truck mounted blowers is 20 PSI. Valves are available for other
applications with temperature compensated pressure settings of between 3 PSI and 24 PSI.
Customer should request set pressure at time of order.
•
High relieving capacity varies between 800 SCFM and 1700 SCFM depending upon the chosen
set pressure. For specific relief rates please refer to our website or contact Dixon™.
•
Installed cup seal deters tampering
•
Anodized aluminum body reduces thread galling
