Abstract: An internal valve includes a valve body, a valve stem, a poppet valve, and a bleed valve. The bleed valve includes a body with a bore. A spring seat fits within the bore and is coupled to the valve stem, and includes a guide sized to receive the valve stem and a flow aperture. The flow aperture defines a connecting bleed path that fluidly connects a bleed flow path and a bleed outlet. The valve stem shifts from a first position where the poppet valve and the bleed valve are closed, to a second position where the bleed valve is open and the poppet valve is closed, and a third position where the poppet valve is open and the bleed valve is closed. A spring disposed in the bore bears against the spring seat and is arranged to close the poppet valve and open the bleed valve.

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 emergency shut-off valve includes a valve body defining an inlet, an outlet, a valve port between the inlet and the outlet, and an aperture. A valve assembly is positioned partially within the valve body and extends through the aperture. An actuator assembly is operatively coupled to the valve assembly to move the valve assembly between an open position and a closed position and includes a poppet and a rotatable shaft. The poppet is disposed within the valve body and is moveable between an open position that allows the flow of fluid through the valve body and a closed position that prevents the flow of fluid through the valve body. The shaft is coupled to the poppet and has a retaining member positioned within a slot in an arm of the poppet to prevent the poppet from being removed from the shaft.

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.

Abstract: An internal valve including a valve body, a poppet valve coupled to the valve body, a bleed valve, a stem slidably disposed in the valve body and operatively coupled to the bleed valve. The stem is shiftable from a first position wherein the poppet valve and the bleed valve are both closed, to a second position wherein the bleed valve is open, and a third position wherein the bleed valve is closed, the poppet valve is open, and the poppet valve may shift toward the closed position and the bleed valve may open in response to a pressure change. A spring seat is coupled to the stem via a retaining feature such that the spring seat is movably disposed in the valve body, and a spring is operatively coupled to the stem via the spring seat and configured to bias the stem toward the first position.

Abstract: An emergency shut-off valve includes a valve assembly positioned within a valve body and an actuator assembly operatively coupled to the valve assembly. A poppet is coupled to a shaft having a retaining member positioned within a slot in an arm of the poppet to prevent the poppet from being removed from the shaft. A gland has a first slot, a second slot opposite the first slot, where the first and second slots are configured to receive an end of a torsion spring, and a flange. An O-ring is positioned within a recess in the valve body at the outer surface to engage the flange to provide a seal between the gland and the valve body.

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.
