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 close in response to a pressure change. The internal valve includes a strainer having an extended portion to be positioned in a clearance space between an upper portion of the valve body and an opening of a fluid container. The strainer is arranged for securement to a mounting area of the valve body by at least one fastener.
