The valve body has central channel extending vertically between a vent opening in the top and a working opening in the bottom and a side channel extending from the central channel to the side surface. A plurality of vertical recesses in the central channel extend from the top of the valve body, having bottoms above the side channel. The shaft seal is attached to the exterior surface of the sliding shaft and moves to seat against the recess bottoms to obstruct air flow between the side channel and the vent opening.
