Abstract:
An internal valve (100) includes a valve stem (106) disposed in a valve body (110), a poppet valve (102) coupled to the stem, and a bleed valve (104) is 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 poppet may shift closed in response to a pressure change. The valve body includes a shoulder arranged (318) for sealing engagement with a container flange (304) and is between an inlet and a flange of the valve body and spaced away from the inlet, the shoulder arranged on the valve body to place the inlet a desired distance away from the inner wall of the fluid container (131).
