    Abstract: A check valve includes a valve body (210) and a valve element (230). The valve body includes an outer circumferential wall (223) extending between an inlet port (221) and an outlet port (222), an inner circumferential wall (245) defining a guide passage extending to a radial wall, one or more outer peripheral flow passages between the inner circumferential wall and the outer circumferential wall and extending from the inlet port to the outlet port, and a valve seat (225) surrounding the inlet port. The valve element is retained in the guide passage and is movable between a closed position and an open position. The valve body includes a body housing (220) defining the outer circumferential wall and a carrier member (240) assembled with the body housing and defining the inner circumferential wall and the radial wall. The valve seat comprises an annular seal member retained between an end face of the carrier member and a counterbore portion of the body housing.

    Abstract: A flow control device includes a body and a flow control element. The body includes a thermal conditioning passage disposed within a side wall, disconnected from a flow passage, and extending between a first conditioning port and a second conditioning port. The thermal conditioning passage has a first portion extending circumferentially around a first circumferential portion of the interior surface of the flow passage, a second portion axially spaced from the first portion by a first axial U-shaped bend and extending circumferentially around the first circumferential portion and a second circumferential portion of the interior surface of the flow passage to form a first circumferential U-shaped bend, and a third portion axially spaced from the second portion by a second axial U-shaped bend and extending circumferentially around the second circumferential portion of the interior surface of the flow passage. The thermal conditioning passage further including a radial passage connecting a central portion of the first circumferential U-shaped bend with one of the first and second conditioning ports.

    Abstract: A fitting for a tube or pipe capable of functioning a high pressures having a first fitting component adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules and a second fitting component that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device against pressure. The retaining portion can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition. A further aspect of the invention includes a first fitting component in which an exterior portion of the component is work hardened radially outward from the tube gripping device. The fitting may optionally be provided with a structure to effect the pull-up by torque functionality.
