Abstract:
An internal valve includes a valve stem disposed in a valve body, a poppet valve coupled to the stem, and a bleed valve coupled to the stem. The valve stem is shiftable from a first position in which the poppet valve and the bleed valve are closed, to a second position in which the bleed valve is open, and a third position in which the bleed valve is closed and the poppet valve is open, and the poppet may shift closed in response to a pressure change. The valve body includes a shoulder that is arranged for sealing engagement with a container flange and is between an inlet and a flange of the valve body and spaced away from the inlet. The shoulder is arranged on the valve body to place the inlet a desired distance away from the inner wall of the fluid container.
