A seal (42) for an air valve having a valve shaft (32) rotatably carried in a bore (36) formed in a body (11) and a valve head (34) carried by the valve shaft (32) to control air flow through an air passage (14) as the valve shaft (32) is rotated. The seal (42) may include a pair of spaced apart sealing members (46) adapted to engage the body (11) within the air passage (14) to seal a junction between the valve and air passage (14). The seal may also include an intermediate member (48) between and interconnecting the sealing members (46), where the intermediate member (48) is flexible to permit movement of at least a portion of the sealing members (46) toward each other and the intermediate member (48) is also resilient to yieldably bias the sealing members (46) away from each other at least when the sealing members (46) are displaced toward each other.
