A valve assembly that includes a valve body, a poppet member, and a biasing member. The valve body has an internal through-channel. The poppet member has an inside portion positioned at least partially inside the through-channel and an outside portion positioned outside the through-channel and extending outwardly beyond the valve body. The poppet member is movable within the through-channel between an open position and a closed position. The biasing member is external to the valve housing and applies a biasing force to the outside portion of the poppet member that biases the poppet member toward the closed position.
