ABSTRACT:
A seal construction for a pneumatic valve (66) reduces resistance to movement of a stem (76) which directs flow through the valve. The seals (78) (108) are generally "v" shaped in cross section. The seals include heel portions (86) (110) which are supported on supporting surfaces (80) (112). The seals include first lip portions (92) (122) that extend from the heel portions to a surface that is moveable relative to the seal. Second lip portions (98) (128) extend from the heel portion to surfaces that are stationary relative to the seal. Spaces (104) (134) between radially extending projections (102) (132) and spaces (90) (120) between axially extending projections (88) (118) enable fluid entering pressure relief areas (106) (136) to escape to atmosphere. The seal construction avoids seal deformation that would otherwise increase resistance to stem movement.
