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. A valve body of the internal valve includes primary and secondary stem guides supported by respective primary and secondary stem struts connected to an inner side of the valve body. The valve body further includes thickened portions extending inwardly toward an axis of the valve body to which the secondary stem struts connect.

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.

Abstract: An internal valve including a body having a first end configured to be disposed within a tank and a second end configured to be disposed outside of the tank. The body includes a shoulder configured to be positioned adjacent to a mounting surface of the tank, a single flange positioned between the shoulder and the second end, a plurality of primary struts connecting an interior of the body to an internal primary stem guide, and a plurality of secondary struts connecting the interior of the body to an internal secondary stem guide. The primary struts and the primary stem guide are positioned between the flange and the shoulder, and the secondary struts and the secondary stem guide are positioned between the shoulder and the first end.
