ABSTRACT:
A dry disconnect coupling assembly which includes a body with a first end flangedly connected to a manifold and a second end releasably secured to an angle valve, for allowing fluid to flow through the coupling assembly. At the point of engagement between the assembly body and the angle valve, there is included a first angle poppit valve for sealably engaging against the inner wall of the flow bore of the angle valve and a check valve for sealably engaging against the internal wall of the assembly body, with the angle poppit valve and the assembly body sealing adjacent one another for providing minimal space therebetween. Should there be a need for a controlled break in the engagement between the angle valve and the assembly body, the poppit valve would be controllably moved to its sealing position by the actuator, and the check valve will be controllably moved to its sealing position by a coil spring, so that any fluid which may be contained in the assembly body will be sealed between the ship's manifold and the assembly check valve, and any fluid which may be contained within the angle valve will be sealed between the poppit valve and the flow bore of the angle valve. The controlled closure of the valves dissipates back pressure buildup in the system, while the positioning of the valving elements results in a minimal amount of fluid spillage left in the space between the two valving elements.
