2182 Blower Air Relief Valve Male NPT, 15 PSI

ApplicationsDesigned specifically for use on tractor mounted air blowers. The 2181 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.FeaturesHigh relieving capacity varies between 800 SCFM and 1700 SCFM depending upon the chosen set pressure.Installed cup seal deters tamperingAnodized aluminum body reduces thread gallingConstructionAluminum anodized hard coatWhite food grade silicone poppet and diaphragmNoteThe 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.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.WARNING: This product contains a chemical known to the State of California to cause birth defects or other reproductive harm.
