2in Male Air Relief Valve set at 20 PSI

Item # 2182/20

2182 Blower Air Relief Valve Male NPT, 20 PSI
Pressure Setting: 20 PSI

2" 20 PSI male air relief valve designed 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.
Type: Spring loaded
Pressure Setting: 20.0 PSIG
Connection Size: 2" male NPT 
Construction material: Aluminum body
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 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. 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 


** Available in many different pressure settings**
