A valve for controlling fluid flow through a flow passage. The valve includes a tubular valve body defining a longitudinal axis and having an interior surface and an exterior surface. The valve body defines first and second valve ends and a tip portion is supported on the valve body and located at the second valve end. A cap member is supported on the valve body and includes an interior surface and an exterior surface and is positioned over the second valve end for movement in a longitudinal direction parallel to the longitudinal axis. The cap member includes an open end and a closed end, and the closed end is formed by an end wall having an aperture for receiving the tip portion. The cap member is movable in a first direction toward the first valve end to position the cap member in a closed position with the tip portion extending through the aperture to prevent fluid flow through the valve body, and the cap member is movable in a second direction away from the first valve end to position the cap member in an open position with the aperture displaced from the tip member to permit fluid flow through the valve body.
