A drill pipe float valve for location in a drill string to allow flow down the drill string but providing a sealed closure against flow upwardly when the downhole pressure exceeds the pressure above the valve. The valve includes a body formed by upper and lower body portions which are threaded together and are separable in a manner to permit easy removal and replacement of an orifice seal element. On re-assembly of the two body portions, the seal element is secured between mating parts in a manner to readily secure the seal element in its operative position and to protect a major portion of the seal element from contact with the flow of fluid through the valve.
