A combination gladhand and shutoff valve for use in tractor and/or trailer applications has a gladhand body with an air inlet and an air outlet. A seal member is positioned at the air outlet and there is a chamber within the body which connects the inlet and outlet. A valve plug is movable within the chamber toward and away from the seal member along a path coaxial with the outlet and the seal member. The valve plug has portions thereon which cooperate with the seal member to close the outlet. A handle is located outside of the gladhand body and is operatively associated with the valve plug for effecting movement thereof between open and closed positions.
A combination gladhand and shutoff valve for use in gladhand coupling applications including a gladhand body having an air inlet and an air outlet, a seal member positioned at said air outlet and having a central passage therein, said seal member being attached to said gladhand body and having a portion thereof positioned exteriorly thereof so as to form a seal with a mating gladhand fitting, a chamber within said body connecting said inlet and outlet, a valve plug movable within said chamber toward and away from said seal member along a path coaxial with said outlet and seal member, said valve plug including a body portion and a nose member mounted thereon, said nose member being movable relative to said body portion to insure alignment of the nose member and the seal member passage when the valve plug is moved to a valve closing position, said valve plug nose member further including a circumferential rim positioned for contact with said seal member radially outside of said central passage to form a seal between said seal member and valve plug in the valve closing position.
A combination gladhand and shutoff valve for use in gladhand coupling applications including a gladhand body having an air inlet and an air outlet, a seal member positioned at said air outlet and having a central passage therein, said seal member being attached to said gladhand body and having a portion thereof positioned exteriorly thereof so as to form a seal with a mating gladhand fitting, a chamber within said body connecting said inlet and outlet, a valve plug movable within said chamber toward and away from said seal member along a path coaxial with said outlet and seal member, said valve plug including a circumferential rim positioned for contact with said seal member radially outside of said central passage to form a seal between said seal member and valve plug in a valve closed position, said valve plug being slidably movable within said chamber, with said valve plug being keyed to said chamber to prevent rotary movement of said valve plug, and handle means located outside of said body and operatively associated with said valve plug for effecting movement thereof between valve open and closed positions.
